I suppose you all know what I am up to here. I have heard anywhere form 300 to 375 horsepower out of the combo I have. Would anyone like to give me a little more info?

350 block. Lets say it is factory cast stuff in there from 1971, rebuilt of course but you know still no Hperetic(sp) or nothing like that

Heads are the 2.02/1.60 (62CC) valve 327 heads

Victor Jr intake
Either Carter or Holley 750 CFM carb

Vaccuum advance HEI distributor

Cam part number PN 3863151 (L79 hi-po 327 from the 60's)here are the specs for those who don't know them.
Flat hydraulic
320* duration at lash point
221* at 0.050 lift
.447 lift w/1.5 rocker
114* LSA
110* ATDC intake centerline
Opening point
intake 40* BTC
exhaust 92* BBC
Closing point
intake 100* ABC
exhaust 48* ATC


What horsepower am I looking at?
What size stall would you use in a 700r4 tranny in a 3400 lb car?
What size gears will work well with this combo?

Thank you!
Jason

85,

Same answer as before...

I had the identical cam profile (Crane) in a 355. It was a pretty successful factory profile, so it was emulated by most of the aftermarket cam manufacturers. That same engine had 2.02/1.60, ported factory iron heads, 1.6:1 stamped rockers w/girdles, 11:1 TRW flats, smaller chambers, trimmed nodular crank, polished beam rods, Performer intake, POS Holley 4160, recurved factory distributor w/CD ignition amplifier, Accel coil, no accessories, and open 1-5/8 headers.

If you promise not to laugh at the "dyno sheet" from the old electrodynamic engine dynamometer, I'll let you take a look:



If you were expecting a printout, this thing was built long before the computer was thought of in automotive engineering. The load was applied and read with analog meters, and the output horsepower was calculated from the torque produced at a given RPM. If you notice the date, you might not be as surprised. Mr. Clendenning's shop is now defunct, but was one of the better ones around for general engine repair and some performance work.

I'm guessing the installed HP will be lower, and the necessarily lower static compression you will probably build to will limit power a bit more. But this should give you a rough idea of the potential.
