Okay, a quick question. After some fun bench racing on Saturday night I have decided to build a seperate 331 or 347 that will go into the '62 at a later date. Now, how many here are running a motor that they have built from the ground up on their own (in your own garage, no pre-built short blocks)? How many are using remanufactured or crate motors (short or long)? And how many are just keeping the motor that came with the car running? Also, for those who built their own motor, what kind of treatment are you giving it, meaning, is it babied as a grocery getter or do you flog it on the drag strip?

My engine has a little history. It was purportedly a crate replacement at a dealership for a 5.0 Mustang. However the owner recognized it as a generic 5.0 without the Mustang specific parts. I flogged it and upgraded it until a rebuild bacame both necessary and possible. I had a local shop turn the crank 10/10 and hone the block, put in cam bearings and I did the rest. It goes like a striped-assed-ape and I flog it pretty hard. It has quality pieces and hasn't shown the slightest complaint.

Ok, this is my kinda topic. ;D The 1994 5.0 HO in my Merc has a stock shortblock with hyper pistons and about 80,000km. I mildly ported the E7 heads, added 1.7 rr's, a weiand action plus intake with a 1" phenolic spacer and a 600 Holley carb. I've got the super comp headers too. I picked it up complete for $1000 from a 94 GT convertible. I beat the shit out of it all the time, but who doesn't do that...LOL ;D
Next up for the 5.0 will be these changes in the fall/winter of 2006: Heavily ported 70 351W heads, 3/8" stud mount 1.6 rr's, E-303 roller cam, weiand stealth intake and a built C4/C5 tranny with extra clutches, Kevlar bands, a loose converter and a ratchet shifter. ;D I'll have it dyno'd again once it's all done. I'd like to see 240+RWHP if possible.
I'm building a twin-turbo 357W for my drag car. Forged slugs, ported E5 heads with 1.7 rr's, Weiand stealth intake, 750 Holley DP, Comp Cams 280H grind, Edelbrock gear drive and etc. I'm using 2 GM 6.5L diesel turbo's and shooting for 600HP at 15 psi of boost. I'll be running a built C4 behind that too. I'll be starting the engine assembly after xmas as the block/crank are freshly machined and hanging on the stand. ;D
Oh yeah, I'm also helping my buddy put these parts on a stock 1994 5.0 GT this winter:
GT40-X305 aluminum heads Edelbrock Performer 5.0 Fuelie intake Pro-Products 70mm TB B-303 roller cam 1.7 rr's FRPP true roller double timing set Custom Mass air sensor
This stuff is already in/on the car: K/N filter kit 9mm FRPP plug wires MAC longtubes and full 2.5" MAC duals with high flow cats. 3.73 FRPP gears
Should be a stout piece, the car is quite fun now. ;D

well the only thats runnin round here right now that i did is the six-two but did it out in the back yard(not even a shade tree for comfort) so i guess i dont qualify cause you said in the garage . took it down to the block-new bearings, rings,two new pistons etc did the valve job meself ;D i flog it that lil 221 like she was built by Smokey Yunick hisself. the way the bottom of them cylinders looked(kinda ate up from that salty air n sittin so long before i got it) i figgered it woulda burnout a couple of rings by now-its been a year= d a m n i do good work i remember A.J. Foyt hisself sayin a loooong time ago "if ya break'em in slow they'll run ........ slow" sold my big block(bare block rebuild) when i moved- the guy hasnt come over ta kick myass yet so i guess its holdin up ;D you build a nice lil hipo motor and then baby it and yur gonna build a nice thick layer of carbon crate motors are nice but you're gonna miss out onna lotta fun and i think you can do a lot more for your money when ya put it together yurself

There's crate motors and there's crate motors. Pick carefully because some of them are time bombs with a fifty-fifty warrantee. Fifty feet or fifty seconds, whichever occurs first. That would be from the door btw, not actually in the car or running.
If.............I bought a crate motor, I would tear it down to the last nut and bolt and check it before putting it back together. Some are advertised as dyno'd but that may just be a sim dyno. That means they hooked it up to an electric motor and spun it until it had oil pressure.

I'm moving the Merc out of the garage to a dedicated work space. a buddy of mine (the buggy builder) has a hanger for is plane at the local muni airport that has a lot of room for projects. It's gonna be nice to have a place that is not cluttered with boxes and dirty laundry to work in. Now, since there is a lot of extra room I thought a engine build up might be in order (I would hate all that space going to waste). Anyway, prices on the Ford crates are a little high, and I would much rather build up my own. I just wanted to hear what was happening with the rest of ya'll and what kind of performance you were getting.
I had a conversation with some local Chevy guys. One was talking about a 350 he built a while ago that lost a main bearing just at the end of the break-in period. The other fellow was saying that the better way to go is just buy a crate and let a pro build it up. I'm thinking that I'm sure that there are shops that build up good motors but those crates out of summit are put together factory style. So how much care has gone into it?

I would be thinking about what level of performance you are going to use the car for. Occasional blasts down the on ramps, laid back cruising, or street warrior saturday night terrorizier, a few passes at the strip? Now look at the pieces you already have that you want to use. That would include the rear end gears, transmission, carbureter and ignition.
Even the 347 or 331 route will put you into having to decide on camshaft, carb, headers and the rest of the goodies.
In other words, get behind the wheel in the garage and let you imagination run wild and spbffffflllllllttttt all over the inside of the windshield until you know what you really want. Figure out early on if you want a roller block. The big advantage there is if you go with a roller cam, it decreases the pucker factor during the engine break in........ Basically you just make sure it won't overheat and drive it. With a flat tappet cam you will have to follow the break in procedure no matter what your gut tells you to do.

if that flat tappet is still runnin in 10 minutes -its good
i got a roller block that i had sittin a while and i decided to tear it down bout two months ago and whatta ya know= a galled lobe AND roller lifter. only bout 88thousand miles on it so.........
ya ever watch a race and bout 50 laps into it somebody blows an engine? or how bout a drag race where it "wont fire" at the line? they didnt plan or build it for that to happen. sometime s h i t really does happen

Has anyone here read that article on the pump gas drags in the current Hot Rod. Now those are some cool cars. Fast and versatile. A road worthy car that runs in the tens is a place to shoot for.
Okay, they say size doesn't matter, but who has the biggest powerplant here. Just sheer displacement. We have a lot of 302s, any strokers or Clevelands here? How about the in registry Stu?

I also like the whole concept of cars that go fast and are entirely streetable. As in drive it across the country with no modifications on pump gas.
If I ever hit the lotto then an all aluminum 427 would find it's way into the Fairlane.

My merc has a mass-produced junk shortblock with freshened up junkyard truck heads, weiand intake and eddy carb. It runs ok, but it is one lazy mill. Revs slow, leaks,modest oil pressure, and the mileage is nothing to write home about. This is of course, when it is in perfect tune. Its going to get pulled this spring/summer.
Building your own shortblock is always a good idea. The fact is, no one is going to care about your motors condition as much as you are. Checking all of the clearances, using good bearings, rings, and pistons is something you can afford when you do the labor yourself. One good thing about the SBF, is the larger lifter diameter (compared to a SBC), us chevy guys feel like we cheated death with a successful hi-po cam break in.

Yeah, some of the fine print on those 350 reman engines is scary. Something to the effect of, "many parts have been re-used from other engines and selected by a lower than minimum wage non-english speaking person who will lose their job if they don't throw them together fast enough." As if the plastic timing cover weren't already scary enough.
I had a nephew that worked as a manager at Schmuck's for a while. He said they changed vendors for the cheapest rebuilds real regular but they always had the same address.
