@davefuckinharris

Think so? Guess you never heard of Mary Pozzi...she has a '73 Camaro with leaf springs and can hang with a Z06 on an autocross. Type in "Mary Pozzi Autocross Highlights" into the youtube search without the quotes. Her car only has a zz383 with 425hp and weighs about 3600lbs, and it was only a couple tenths behind a Z06 Vette in the video.

@70camaro406 well idk about the leafs but she did say that her aftermarket suspension was from hodgekiss and thats a sweet car too

@davefuckinharris

Well, I do since I know her, and it has Global West leaf springs with articulating bushings in the rear, Hotchkis coil springs in front, and QA1 double adjustable shocks all around, with a Hotchkis sway bar in front.

That thing sounds sweet and looks better than my '69. And you have the same camera man as me...

[70camaro406]

No, you'll need at least 110 octane for that. Depending on the motor, the maximum safe compression ratio to use pump gas is around 11:1...but like I said, different variables such as lobe separation, duration, converter, and timing can vary that number a bit.

cool. also, is 13 1/2 compression safe with 93 octane?

[70camaro406]

Solid rollers are better in racing applications than hydraulic rollers, which are a bit heavier and can't rev as high as the solids...same goes for flat tappet lifters.

[sk8forlife90]

are roller cams better than hydralyics?
