The L79 may have been advertised as 11.0:1, but trust me, it was less than that in reality. Treat this cam choice just like any other, match the intake closing point to the static compression ratio, figure your DCR and go with it. Actually, if I were going to build it, I might use a solid flat tappet cam and use the solid tappets with the 0.012" oil holes. The first motor I ever heard lope with a solid lifter cam just blew me away. It was a brand new '56 Chevy that idled sounding like potato, potato, potato, potato and the solids ticking just mesmerized me. I was 14 at the time.....and ruined forever.

P.S. Most all the OEM's have used wide lobe separation angles in the everyday motors because grandma does not want the motor loping on her way to bingo.

this junk(was junk when I finished with machining) went into a 64 chevyII. actually went fairly well
his lil 283 would go.He wuz a character tho.He wanted wider tires on the rear but couldn't afford a set of air shocks,so,he jacked the rear up to extend the shocks,then cut pieces of pipe & slid the pipe over the shocks to keep it up in the air.Talk about a ruff ride.LOL.When the lil motor got wore,he kept 2 1 quart coke bottles of 90 wt gear oil tied between the grill & radiator.He would run around the corner,pour a qt in so nobody would see him.It ran a long time like that.

for a 327 in an old Impala this is what I would want:
10.2:1
AFR 195s (or equal)
750 double pumper on a good intake(most people like the performer RPM)
1 3/4 tube headers
111203-10 NA 269 269 237 237 .555 .555 110 106 .022 .022 1,2,5
2500-6500 Rough idle, Street Performance/mild Strip. Recommend 9.5:1 CR, 2500+ stall.
a cam like this
4.11 gears
3500 stall if auto
you could always slow the car down a little to run 14s

Vinnie, pardon my ignorance, but what do the numbers 1,2,5 represent at the end of the cam specs?

I noticed Comp tightened LSA up from 114 to 112.They gave it more lift as well,but,gave the intake higher lift.An article I read said this cam(the original 151 cam) in the L79 wouldn't idle with a stock convertor.If Grandma could drive a stick,she was good to go.

So it's BBC, ?????? Just want to clarify, i know 427 SBC is attainable . Im in Australia , not 'super' conversant with cubic inch SBC/BBC combinations. Sounds like a very efficient exhaust system....I'm going with a big block,,,,let's know..


Duke

Mmm...227 heads? Maybe sbc??
