OK, i recently traded my r6 for my first 5.0! It already has BBK CAI, headers, and a h-pipe. My questions are one) This summer i am planing on doing a build up, I cant decide whether to stick with the 5.0, or throw in the 5.8 short block i have sitting in my garage. I dont really know what swapping the 5.8 involves as far as fuel pump, intake, computer, and stuff like that goes. Would it be too much of a hassle to drop in the bigger motor? What all would i have to change? This isnt my daily driver and i want to make this thing fast!! What do yall recommend as far as Heads, intake, cam for the 351 and/or the 302. Thanks for the input!

depends on what year your car is. the swap should be fairly simple from what i have read. i am planning on puttin the 351 in mine too. What year r6 did u trade?

351w swap, convertable motor mounts sit the motor lower, so thats a must, a cowl hoos is a must still. trick flow makes a great intake for a efi 351, trick flow makes great heads to. the computer you should not have trouble with.

you arnt by chance related to jeff merril are you?

nmerrill

no, i dont think we have any Jeff's in our family, but i do know a Jeff Merrill. does this guy live in texas? And my stang already has a cowl hood so im good there! also, i am pretty confident i am gonna go with the trick flow whole set up, heads, cam, intake etc.... but can i get it for my 351?

the heads, cam and upper intake can be used on your 351, but the lower is different b/c the 351 has a different deck height.

Where are you in TX? I'm in Dallas (Carrollton, actually)....

The 351 uses 1/2" head bolts whereas the 302 uses 7/16" bolts.
