Thread: safe compression ratio

Oh yeah, sorry Tech.....should of mentioned... This will be backed by a 5 speed, and "streetability" is just a matter of interpretation.... Basic purpose will be a Saturday Night Special, good manners and mpg is not a consideration...... Cam will be a roller, to get the correct specs having to go mechanical roller is really a non-issue, I don't mind adjusting valves. No daily driver criteria applies, got my trusty-rusty Escort for that!!!!

Should have been a bit more specific, I guess....

Well, ok, but you'll still have to slip the clutch to get the motor from idle to the lower operating range of the cam. I guess it all depends on how much slipping you're willin' to put up with. I'll stick with my original combo and add a 4.30 or better rear gear. YOWZA.

I'll keep the weight down in the 2400 to 2600 range, and of course with the five speed I can get quite deep on the low and second ratio, spread third a bit, 4th at 1:1, and probably a .72 or so overdrive..... Heck, clutch discs are cheap and I love to shift anyway!!!!!!!!

PS--I've been known to run a set of 6.00's on a spool for really "special occasions"!!!!
