351w Efi & Roller Conversion

[91redFox]

Hey guys,

I've been looking a lot into doing a 351 swap on my 91GT. I am looking at both the c9-D4 (1969-1974) blocks as well as the F4TE blocks. I know the F4TE blocks are a lot weaker, although I don't know if this will really be an issue with my power goals (somewhere between 450-500RWHP, Will most likely be a turbo build).

If I did decide to go with the stronger 69-74 block, what is a rough estimate of what it would cost me to do an EFI and Roller conversion?

A good link bar style conversion is expensive, I think it was south of $1000 when I had the 410w. Could be cheaper now.
If you can find a roller block, that's the route to take. The difference in available cam profile is worth it

You can get a very nice morel lifter for under 500 bucks, as far as efi goes, it could cost you anywhere from $400 to $3000 depending on how you do it.

And just fwiw the roller block is good to around 7-800 hp
