So who in here races a 318?

My 318 street Dart runs mid 13s at 3,350 lbs. It ran in the high 14s until we swapped to a set of milled 318 heads with larger valves. It was my first engine build. Can't wait to get back and drive it again.

Unless your using 318 heads none of these combinations are 318 anymore...

That is amazing! I had no idea that we didn't have to do any bore and stroke changes. Which heads will give me the most displacement? LOL=P~

Some of you guys are a little confused about 318's. Aside from block strength issues (there are ways to help that), 318's are just 340's with a smaller bore. If we wanna talk about hot rodded 318's, let's do that.

Hmmmm, here's one:

I have a 67 barracuda fastback thta I take to the track a few times a year. Its a 318 .030 over, hughes engines heads, 1.94/1.60 valves, performer rpm airgap, demon 750 annular mechanical, with 1' open spacer, headers, engle cam [email protected], roller rockers, 904 trany, w manual valve body, 4.10 gears, auburn posi, caltracs, holley electric fuel pump, many fiberglass components..Runs 13.07 @ 102.7 time slips show 12.98 is in it under right conditions.......60 ft. 1.75 best....shift at 6,000 through traps at 5900..
want to change to a 4.30 in the future.....

You did not say what your compression or lift is but.....my thoughts?.....keep the gears you have and put a Clay Smith C-304-6-B solid cam in it. It's 258 at .050" and .525" lift with a hot lash of .024" using 1.5 rockers. You'll probably run 12.50's.
Just a thought.
