Should do both,a turbo 351W with blow thou carb set-up .

It would make more power than the 302 and would be more durable.

Then he should do a turbo and keep it FI.

If you're going to convert to a carbed turbo, the 351w way is actually cheaper. You can buy a short block for under 1500, victor heads under 1500, and cam and intake....another 300 or so......turbo kit for 5.0.....usually around 3200 and up.....then if you convert that to carbed instead of FI.....PITA! but then again, 351 swap isn't the easiest always. If he's doing 1/8th mile runs, then turbo is not the way to go really though......boils down to what he really likes more......all motor or annoying blow off valve

Is nitrous an option?

Carbed 351W with nitrous will run that.

Or if your daring,you could put a 250 shot to the 302.

hes stuck on going turbo so I am trying to tell him to keep the FI and not go with the blow thru carb , but hes reading all this stuff on turbo mustang forum about the CSU carbs , and figuring up how much its gonna cost to change it over and I am looking at it like this , just the carb is $750 ? so I can get a deal on a set of VIC jr heads for $960 so why not build a stroked 5.0 and keep spraying or even stroked 5.8 with spray and better heads and intake .....

Whats so hard about either?

Maybe you prefer carb...which i dont really understand if you are already FI, but thats your opinion. Once you have the parts for the 351, IMO its a drop in a go. No harder than any other swap.

A carb setup with forced induction can be a nightmare to tune a lot of times. One day it runs great, another it's different weather and it doesn't want to run right. EFI comes standard on all vehicles these days for many reasons - save the nightmares and just keep it EFI.

You get thous heads,find a 351W shortblock and build it up and put it on spray.

And no baby shots either,200-250hp .

What evers cheaper.

You could sell all the FI stuff a buy a carbed set-up or you can get a lower for the 351W and put a big shot plate in between

Personally i would build a 351 and put a junkyard turbo setup on it. Depending on how fast you want to go, just put a turbo on the 302. I have jus recently fell in love with turbos so thats where im going. Vrooooooomm.......PSHHHHH

Well I did the blowthrough carbed setup on a 342 and its interesting to say the least. Tuning isnt too fun but the carb doesnt cost that much. You can get a proform prepped carb for like $400. You can tune it yourself and if you can plumb your own setup you'll save there. Best to keep it fuelie though or go with the 351.
