Who has the most smoke with the least...

Amount of compression?

Lets here about some low compression combos haulin' ass.:3gears:

 

Where's that Miller guy with the low compression 73 Stage Buick?? :3gears:

 

Ok I will go first, Compression ratio 10.25:1 13.13 @ 106.05.. Not sure thats considered low compression ..

 

I think he meant the smogger motors.Like 73 455 TA's-455 Old's and such.

 

Mine is definatly definatly not a Smogger lol .. I guess lets let him clairify his statement ...

 

I talked to Tom on the phone thats what he meant.

 

there is no telling for sure, but Larry Weymouth's 71 LS6 11.94 with 9.0:1 advertized compression.........

Dan Jenson went 12.55 and Pete Germani went 12.59 with a 71 Pontiac 455 rated at 9.5:1

John Glasco has gone 12.61 and Charlie Lombardi has gone 12.73 with a 73 Pontiac 455 rated at 8.98:1

Tom Miller is tops in the smogger Oldsmobile with a 12.91 in a 72 455 with 9.16:1

Matt Hammond has the fastest AMC at 13.87 in a 73 401 with 8.83:1

Mike McPhillips went 14.23 in the fastest Fors in a 72 351 with 9.4:1

James Jacob had the fastest smog Plymouth at 14.42 in a 74 360 at 9.02:1

Buicks stayed at 10.5:1 through 1974

 

I was refering to the "newer" muscle, 71 cars and such.

That is a nice little list Donny

 

"Buicks stayed at 10.5:1 through 1974"

No, it was 1970

 

got a low compression 430 in a 70 gs. 8.58:1 CR and runs 12.20 @109.

 

I went 12.95 @ 110mph with my 71ls6, I hope it does better this year with the new MR 6 PACK GM CAM and NHRA blue printed motor. If larrys car is any indication, I should be able to close the gap a little, as he is 1 second faster

 

I took the numbers off the NHRA blueprint specs.........
they seemed odd at the time.


if that is the case then Greg Gessler would be the man with a 12.42 in a '72 455 rated at 8.5:1

 

Buick dropped to 8.5to1 in 1971.

Donny, stay on topic, this is a Pure Stock thread:Smarty: I think even Greg will tell you that the car was SA at that time,then again, maybe it wasn't?? I know he made the move to F.A.S.T. shortly after, although going much quicker.

 

I was wrong anyways, Chris Robertson in his '70 Buick went 12.31 ........... unless Tom is right, then Joe Sheppard went 12.91 in his 72 455

 

70 is high compression.
I thought this post was about smog motor's?uzzled:

 

Like I said, the NHRA specs show them all at 10.5 through 74...........

so, I dunno o No:

 

My 72 skylark has 8.5:1 runs 87 octane it runs 12.81 at 107 mph. Small valve iron head(gasket matched), B4B intake, 26" tire, 3.55 gear, 2500 stall, 1 7/8 headers, 3800 lbs with driver.

 

NHRA has the specs whacky on *several* combos...and I'll just leave it at that!

 

So is this thread discussing:
-- Factory rated compression
-- NHRA (and PSMCDR) allowable compression
-- Actual, measured compression
o No:
Big difference in many cases.

 

Agreed. I was thinking about the folks that compete at the Pure Stock Drags.
