My dilemma: New proud owner of 69 Dart (with 318) & I want this to be a street/strip car, mostly street but when/if I go to track (maybe half dozen times a summer) would like it to be a mid 11 to low 11 car, but we all now how that changes....

BTW this is not a #s matching car, so mods and slight cut up is no problem.

I have a mildly done 440, .509, M1, stock bottom end, nice set of cast iron heads (done by Nick) IIRC currently a 9:1 motor that I would like to bump up the compression on and maybe go up a notch or two in cams (this 440 powered a 3850lb 69 B body to 12.50's on street tires and very average suspension at best).

Question is what would be the better approach with my goal as stated above, continue improving on the 440 I already own (how much $ and upgrades I would need not sure) or build up a SB (maybe something like a new 360 stroker etc....).

Looking for opinions on the pros v cons, I'm sure some consider this one of those never ending debates. Weight, money, fit etc...

Fire away.
