402 stroker 12.1 compression guess I'm building a high compression 12.1 402 with heavily worked 243s, the cam is a 244/248 612/615 112lsa pacesetter 1 3/4 long tubes catless, fast 102 intake port matched and a xair otr cold air intake. Any guesses on wheel hp
still lots of variables we don't know. auto or m6 ? single 3" exhaust ? bigger maf than stock or speed density with big piping ? should be around 600 or so fwhp so i'll wildly guess if m6 525-540 rwhp, 500 rwtq.
