Is he using a factory 302 block, R block, Dart block?
If you already have a good aftermarket or R block, then its hard to justify the swap to a 351 based motor. If starting from scratch there is ZERO reason other than class racing to stay 302 based.
If you have a good block, I vote 363 with an 88mm minimum.
If you go 351 I vote 427+ci with twin billet 76's
Orrrrrrrr ERL 427, LS based, twin 7675s
