Engine 351w Swap

[Dave34]

i want to build a 351w and push it to 700hp. i have a 72 block and im planing on putting h beams with dished pistons, i also want to convert it to a roller cam and use ported stock heads for now with head studs and my turbo kit for my 5.0 will the stock pistons and crank hold up i heard that they are stronger than the blocks but i want to make sure before i build this motor

 

[Dave34]

i left out upgrading the valve springs because its just common sense to upgrade them with a bigger cam

Stock pistons- or dished ? How much boost ?

If I could do it all again, I would build a 393 stroker....just needs stroker crank...stock length rods...302 pistons and add boost from there.

 

[Dave34]

i was wanting to use dished pistons i believe the non ho motors had dished pistons and ill look into the 393 stroker

700 with stock heads will be a stretch.... a 363 with ported 170cc trick flow heads turbo cam and 14psi made 700......

 

[Dave34]

im still thinking of what im doing with the build ill probably end up going with aluminum heads im just trying to get an idea of what i have to do

 

[a91what]

Ok. What stock heads do you have? Force feed enough boost to it and you will reach the goal.

 

[Dave34]

i just looked at them and i couldn't find any numbers but the block is 72 and the motor was all stock when i bought it
