Is it possible and how easy is it to get an F28 to fit into me nova when i get a valver put in. Also, whats the best way to get about 230-240 bhp from a 16v engine, and should i rebuild the engine when i buy it?? As i want a decent engine. also, whats the advantage of re-boring, oversized pistons, re-ground crank, and lightening and balancing the whole engine??
