Default 302efi to 351 carb conversion

what is needed for a 302 efi to 351 carb conversion? i've got a 351 out of an old truck that i'd like to swap for.. the stock hp rating on this 351 is only 170-ish, what is the most restrictive thing on the 1984 carb 351 out of a f150?

I would find a 351W out of a 94+ truck. They are roller cammed.

check out the sticky at the top of the forum, lots of good info there. as far as restrictions on a stock 351w well just about everything is, intake sucks, cylinder heads are a joke and the exhaust manifolds are better off as door stops. basically keep the block, crank and rods everything else send to the scrap pile! but as far as individual swap components youll need a oil pan, swap headers, and a 157 tooth 28oz imbalance flywheel or flexplate. and depending on your intake maybe a cowl hood also.

ok thanks, if i want it to be a roller motor i can just put my 302 lifters/cam in it according to the sticky
it says i need a 28.2oz flywheel, would the flywheel on the 1984 f150 be 28.2oz?
