Camshaft Selection Information

Don't believe the 390hp output from that magazine engine done years ago, not going to happen with a 268H and bone stock heads.

Running the XE274H, true 10:1, promaxx heads with headers and a good tune will get you in the 400+hp range. We had a 340 cleaned up eddys, XS282S, victor, 750dp, tti's and it made right at 435hp. Ran like it at the track too. Was a solid mid 11's car, 117-118 mph in a piggy weight 73 Duster.
