As much documentation as I have done, probably should not get too far into this 350 long block build but I will. I should probably leave it at suffice to say it is probably the poster child for how not to build a small block Chevy, lol. However I will expand on that a bit. I had a pile of used parts and wanted to know just what I could get away with building a Chevy V8. Lets just say it is not as bad as many remans I have seen, but it is a complete and total mismatch of parts. Also has some stuff done that some would feel sketchy at best.

The block was a Goodwrench L31 pulled at ~120K miles with cracked heads and an oil pan full of coolant and oil mix. The crank had some wear on it and there was bearing material from the rod bearings in the pan. I blew the engine completely apart, cleaned it all up. I probably should of pulled cam bearings, I did not. I put a L30 marine crank from a freeze cracked engine in it after emory clothing some very light surface rust off the journals.

I matched the home polished L30 marine crank with a set of LT1 pistons and powdered metal rods from 2 different LT1s I had previously torn down. I used the rods and pistons that matched in weight closest to the L30 rods and pistons from that cracked block boat engine. The 8 LT1 pistons and rods I ended up using were the ones in the best condition, having the least wear and in the middle weight wise of the heaviest and lightest L30 pistons and rods that had been on the crank pins of that crank. Measured both weights with the rings installed.

I had a set of upper and lower compression rings that matched the LT1 pistons ring dimensions and the 4.00 bore size. IIRC they were actually part of a Mahle 87-92 Ford 302 HO ring set that a buddy just gave me a few years back thinking it was a SBC ring set when I bought a set of new 6.0" SBC H-beam rods and a few other small block parts dirt cheap from him when he decided he was only going to build big blocks. As such the oil control rings did not match, I cleaned and re-used the used LT1 rings rather than buying the $120 metric LT1 ring set.

The cylinder walls were in such good shape, I never even put a hone to them. I felt disturbing the factory crosshatch in the bores as well as increasing the piston to bore clearence would be a step backwards taking material off the bores. The cylinder heads and block face were not resurfaced, but I still used extremely thin Felpro rubber embossed 0.016" compressed steel shim head gaskets to help bump the compression and get a more ideal quench distance.

The oil pump was a cleaned and re-used big block pump with a matching pickup for a small block depth pan. The timing set is a 120K mile single roller from that engine that looked new and was not sloppy at all. When I degreed the cam, the camshaft immediately changed direction in response to moving the crank the opposite direction.

When I set these heads up, I intended to use them on the 97 and run with the a 7395' Marine aka Ramjet/HT383 cam and 1.6 rockers. As such, I skipped adding the more fragile 0.050" offset retainers to compensate for the difference in installed height of the LS6 valve springs. The LS6 springs are thus at an installed height of 1.74" vs 1.80" of a LS. They are rated 0.550" at the 1.80" installed height, which means they are actually rated to 0.490" at their current installed height. The 7395 cam and 1.6 rocker combination skates under at 0.481" lift on the exhaust side and the 15-20 lbs or so of added seat pressure to me was not a big deal with such a small cam and the heavier SBC valves and valvetrain. The 6492 cam I ended up using actually has 0.496" exhaust lift with the 1.6 rocker, thus the springs are actually running 0.006" lift over their rated lift spec. Then again GMPP states 0.550 and the LS6 cam has a bit more lift than that (0.554") as do most of the aftermarket LS grinds calling for those springs, very highly doubt it is a real issue at all.

The GM roller lifters are actually out of a couple different engines, I picked the ones that had the smoothest rollers and least wear on the bodies. Took each one apart, one at a time, cleaned them, cleaned the internals and put them back together. When I put them in the engine, I matched the largest OD lifters to the lifter bores that had the largest ID and continued down the line until eventually the smallest OD lifters were in the smallest ID lifter bores.

Using all the spare and used parts laying around, excluding the Proflow 4 setup and exhaudt manifolds, I do not have $500 in the whole long block including the $100 core charge, new Felpro head gaskets, new head bolts, new 1-piece oil pan gasket, Summit bargain cave Holley L31 aluminum timing cover, $105 GM 6492' roller cam. That is even counting the LS6 springs and Comp 787 retainers I purchased close to a decade ago that I had previously set those heads up with. Except the head gaskets and oil pan gaskets, every other gasket or seal in that engine was from a box of new gaskets I have leftover from 20 years of working on small blocks and GM engines. The heads themself are Chinese thick cast Speedmaster Vortecs that came on a Tahoe I bought with a rod knocking bottom end and put a different used engine into. I ended up buying a $120 reman AD244 alternator from Oreilly, but the rest of the accessories are all used straight out of the spare parts stash. I did go ahead and also invest in a new plastic fan blade and a new fan clutch because of the nature of re-using unknown parts there possibly allowing fans to blow apart and take out things.

It honestly though, blows my mind how well the thing runs, how consistent and even the compression is cylinder to cylinder, how smooth the engine idles and revs and how the rings have already seated well enough, that with the fixed orifice style LS PCV "valve" the crankcase vent tube builds vacuum nearly instantly from that tiny 0.080" or so hole in it. It has virtually no blowby at all and I bet the rings seat even better with some miles put on it.

Re: Electrical problem!! soundhd February 27th 2024 11:43 pm
I agree with Wedge…..electrical problems can be a problem with a newer vehicle but with an older vehicle it can be a nightmare….First thing you needed to do (which you did) was to get a copy of the electrical manual….next get a copy of the shop manual….. First thing you need to check are all the ground points….and do not just look at them…you need to loosen the bolt the ground strap/cable, clean around the bolt hole nd sand it down to bare metal, do the same with the strap/cable then reinstall and if possible coat the assembled connection with shot of paint or some sort of sealer. You will need to do this with all the ground points, the manuals will help alot…..yeah I know it going to be a pain in the rear but 1st it’s the cheapest step and alot of times it cures all the weird electrical problems going on now and later. Hope this helps.
