few questions for the new 347

dderek said:

have a 347 shortblock in the garage, fully forged. should be around 10.5:1 comression with my heads, heads are cnc ported/polished twisted wedge heads. looking to change to a custom cam after i get the heads flowbenched. upgrading from 24lb injectors to 42, overkill i know. but oh well.

anyways, do you think my 190lph fuel pump is enough? or should i buy a 255?

now, im going to get new headers. mine are rusted beyond belief and are garbage.
what size header should i get? 1 3/4" ... 1 5/8"?
the rest of my exhaust is flowmaster 2.5" catback, and im thinking about getting a mac prochamber to replace the crappy custom made X pipe in there. the 3 bolt flange from the header to xpipe leaks constantly. could never make it seal right.

Also, im getting a miloden 7 quart oil pan, that kicks out. so i need headers that will clear that without a hammer

Anyways, let me hear your opinions on fuel pumps, and longtube headers

Thanks
Derek

I'd go with the 255 pump. Definately 13/4" longtubes with 3" exhaust, and a Canton 7qt pan without a kickout. Kicked out pans can be a pain with longtubes. I've always stayed away from them.
