BBC heads
I have posted about head recomendation before..but I am getting ready to purchase something...but I still don't know which ones to get. I have it narrowed to either -2x brodix with 340 cc intake ports or the AFR but can't decide between 325 and the 345. Motor is a 13.1 540 with a solid roller .726 int .737 exh dur at 50 around 274 int 284 exh ..can't remember exactly don't have card with me...but the question is "What size intake ports would be best for a 540 ci 7000 rpm max? " The prices are the same for 325 or 345. They sell a cnc ported 335 also and a 357 for much more money. I want to get the right ones but don't want to go too big. Again this is a 7000 rpm motor. Car is 3050 lb 1/8 mile bracket car with powerglide with brake. 5.14 gears and 32 x 14 tires. 5500 converter
