so i am about to finish my 351w swap. i have a chance to get a tfs stage 2 cam for 100 bucks. my 351w is a 95 roller block with all stock internals. i have world sr heads and a victor jr intake. i know every one is goin to say i need to check ptv but i just wanted to know if anyone would think that it would fit without ptv issues. so i dont waste my money and then have to get a different cam thanks guys

nobody can tell you if it will clear. your heads may have been decked, the block may have been decked, the pistons could have small reliefs, or ones that aren't deep enough. there are many other factors other than parts selection. Even if the tfs2 doesn't fit, you can just sell it off and not lose anything.

yea i figured i know the block hasn't been i guess i was more lookin for a close or and no way in hell

Well, considering the World Sr. heads have a 2.02" intake valve... I'm gonna go ahead and say no. PtV checks will be the only way to know for sure. I strongly suggest that you use the clay method and measure radial clearance. If you already had 2.1" reliefs in the pistons, I'd say you should be good... but stick reliefs are barely over 1.9"

this is what the reliefs look like

so do u think a tfs stage 1 would be a safe bet

get the tfs2, and if your PtV sucks, notch the pistons.

don't be a *****!

Why are you wanting a cam designed for 302's to be put in a 351?
If you end up notching the pistons which I'm sure you will have to anyways get something that can take advantage of the extra ci

how much dose it cost to have the pistons notched
