Hello all motor heads.I am building a early 327 with # 462 casting cyl. heads.Staying with 1.94 intakes and 1.50 exhausts.Using KB flat top cast pistons and .030 overbore.Need to know approximate compression ratio with this combo.Thanks K.N.
I run 10.7 to 11.5 on regular gas, crapgas what ever you call it.the carb heads and cam all have to match then no problem, and I don't drive like a old man, the jimmys got a 406 in it with a real 10.3 compression and runs all the way to 220klics with not a ping
What carb and cam do you run?
a simple quad modified of course, a farely small .500 lift roller cam stock cast manifolds for a 77 and crappy 882 heads, if you want all the specs I can give them to you, the speed shop figure close too 500 horse, and that's through a automatic with a tight torque. ive got specs for a 420 horse 327 that get 25 27 mpg
