347 build?
heres my dilema im wondering if its worth building up a 302 to a 347 stroker or would i be better off jus getting a 351? which would have more power if they both ran flat tops with gt40 heads which would be around 9.1 or 9.5 with a decent low to mid cam and a dual plane intake whjat do you guys think im trying to do this on a budget so keep that in mind

how do you get a 347 with "windsor stock stroke"?? you cant underbore a 351 unless you sleeve it, and a 302 based needs a 3.40" stroke to get to a 347 with a .030" bore...unless youre just changing the rod length, but wouldnt that run the pistons into the heads?? im just wondering
and either way, granted you are on a budget but either a GT40p or a GT40x head will hamper the performance potential. your best bet would be at least a 185cc head to get all the airflow that engine would need to perform to its max
