Thread: 350 build up help

Tweet

Okay found that article, it is from a 1994 issue mag. This motor is best used with a gearing of 3.08 to 2.78 ratios for a fun to drive car.Even at 1500 rpm the engine produced 312 ft/lbs of torque and dipped slightly at 2000 rpm and then quickly regained ground and leveled off, making approximately 380 ft/lbs from 3500 to 4250 rpm. Final tuning and jetting changes saw the HP figures at 364 HP at 5500 rpm and 396 FT/lb at 4000 rpm.

This article lists all parts, right down to distributor timing and type of spark plugs ! So it is pretty detailed if interested let me know.

Oh yeah, running 2 bolt block, cast iron chevy crank, 487X head castings (common) machined down to a 70 cc chamber giving a static compression ratio of 9.8 to 1 with TRW flat top L2417 flat top pistons. The static compression ratio is high but the excellent cam matched with this engine gives a bang on dynamic compression ratio.

This article is big so who wants it up on the forums ?

Not trying to take anything away from the southerner but I would never put any money in a stock head when you can buy brand new cast iron heads for less than $ 600 already with screw-in studs and guide plates not to mention they are much stronger and will make more hp.
I also doubt if you need forged pistons for what you are doing.
I would try a set of Hypereutectic instead.

I agree this article was printed in 1994 so forged pistons were cheaper then. And you can also get a good set of rods cheaper than rebuilding the old chevy rods. And there wern't that many aftermarket heads around either. BUT... The only machining jobs on the heads were a 3 angle valve job and the heads planed, and the valve guides redone.

What I will do is get the article formated and and up under heading 350 350 HP buildup.
