I recently bought a 1973 atc 70. I love this thing... I Just purchased a 88cc head and a pro race cam from dratv.com using the stock head w/some port and polish. I ported intake, Intake tube and carberater, and upped the jet. NoW I also odered the high compression head gasket 52mm/.016"=.38mm. What kind of compression ratio am I looking at?What Kind of power Am i looking at?
Ps. Im having A grudge drag race against a friend. He has A stock 97 Z50...Who do you think will win !!!
