Default 351 vs 302 Delima??

Ok here is the deal i was offered a really good deal on a 96 351W Roller motor complete.The motor made stock 210hp and 320Tq .Its from a 96 F-350 truck. My dilema is i still have those GT-40P heads and a E-303 cam. I know they will fit and i have read what i need to do a swap into my 88LX.But here is the other problem What motor will make more Hp with these mods on both 302/351W? Will my T5 work with a 351? I know more Cubes makes more HP but in this case same mods done to each motor what one will beifet the most?The engine is 200 bucks and needs a rebuild.Here is the list of items gonna be on either engine.GT40P heads,Upper Typhoon Intake,70 TB,73MM,E-303 cam and im gonna have the heads milled .010 for better compression. I could use a Eldelbrok carb and get a new intake. Well any help with this would be great thanks alot. Oh i dont wanna Stroke yet or bore unless needed. [&:]

I'd go with the 351 roller motor but you might need to get a cowl hood for sufficient clearance as the 351 is a taller motor than the 302. Overall, the 351 is a stronger block and will definitely put out more HP and torque if you choose the right pieces to build it with.

If that guy is selling you a 351 for 200 bucks I would be careful, rebuild or not that is a fishy price. I think if you really want a 351 just buy a bare block and swap out all your compatible 302 peices into it, less risky. Just a suggestion
