Bracket Race Engine
Had a friend put together a temporary junk motor out of cheap and old parts he had laying around. Lots of Naysayers.
377" Small Block Chevy (4.125" x 3.75")
Stock 350 2-Bolt Block with hone job.
Stock 400 Crank unturned and unbalanced.
Stock 400 5.565" Rods with stock bolts.
Stock Replacement Bearings (NAPA)
Stock Oil Pump
NOS GM Pistons TRW 11:1 LT1 350 Forged (PAW used to get $99.99 for these).
Iron Rebuilder Rings (NAPA)
Dart Iron Sportsman with home pocket and good valve job (These were $599 a pair in the old days).
Ultradyne Flat Tappet Claimer Cam ($60) with OEM GM Lifters ($20).
Weiand Team G Intake
Old 750 DP Holley Race Carb
6.70 at 100 mph (1.76 Powerglide) at 3,000 lb (1/8 mi).
500 bhp based on trap which is likely a low estimate due to the converter losses.
It spun a bearing last weekend.
It needed oil changes, plugs and several sets of cheap Z28 valve springs over 17 years. Those were the original bearings from 17 years ago.
We go WAY faster now but sometimes I think it's lots less fun.
Edit: Got curious and went diving in my old references.
Camshaft Specs -
Solid Flat Tappet 285/295(0.020) 252/261(0.050) 0.525/0.525 106LSA.
If anybody wants one I think Bullet Cams could set you up as they have all Harold's old (Ultradyne) masters. Better cams today but that one would run on cheap springs and made good power.
