Im in such a debate on what to do... First off the basic goal(430-450rwhp and 480-500 rwtq mid 11's in a fox(3200lbs) to get that power, Im going to have/do H/C/I w/ Kenne bell(9psi). I realize thats pushing the limits of the stock 302 block, which im ok with. Now to the debate. For the amount ill have invested into the motor by either rebuilding my current 302, or going with a all new rebuilt 351w. I know the 302 will be cheaper overall, but riskier b/c im pushing the block limits w/ hp. Now I can have it less riskier by buying a 351w, that will hold the power but add alot more complications to do the swap, and is possible the KB will not work with the 351 deck high on a gt-40(lighting)lower. So the debate is should I just stick with the rebuilt 302-306 H/C/I Kb 9psi, or spend more/add more complications w/ 351w h/c/i kb 9psi that will handle the power better...what would you do if you had the money. Note> I like the simplicity if the 302(less work invloved), but it seems that 351w(more work involved) may be better, but I Dont know. also its not a track car, its a daily driver, that has to pass Ca emissions, that will see track pretty often.
