So stangers how much better is a 306 than the stock 302? Does those 4 cubic inches make a big power /MPG diff?
Atleast 50-100 more HP and MPG.
so what 1/4 mile times are you guy running with the 306?
The same as my 160k 302 bottomend...
I ran 8.27 at 87.31mph with not tune, no burnout on drag radials, all accessories (p/s and a/c, etc), 3400lb race weight.
I gained 1.3mph by getting my 302 rebuilt to a 306, adding longtubes, and ported intake. So...
You ran an 8.27 with a stock 5.0 at only 87 mph? Please tell me you mean 18.27...
You ran an 8.27 with a stock 5.0 at only 87 mph? Please tell me you mean 18.27...
at the very least, usually up to 250hp+++ and will put you around 35mpg.
