Help me get into the 12's for cheap

La 360, I just built mine, easy to get power out of from what I've been told. Although good engines the 318 lack the stroke of the 360 as already mentioned.

I have a 73 swinger as well, my combo is a la 360, kb .30 over 107 pistons, eddy rpm heads to create 10.6: compression, comp XE268 cam, weiand aluminum intake, and a holly 650, and a set of dougs long tube headers. Mind you my build is a bit more spendy you can achieve similar with used/stock-ish parts.

No idea how fast the car will run on the quarter mile but I'll be happy with 13-14s.

What trans are you running? the stock 904? some work to that wouldn't hurt.
