agreed.

You guys are more positive about the GT-40 then I am, I wouldn't run it on a stock 351.

Regardless of whether a 302 or 351 block is used it is planned to beef up the tranny, and redo the induction setup. For a street car would you say it's worth the money to go with say a 393 as opposed to a 347 even if you plan to keep the induction setup on the conservative side?

Get ready to spend close to a $1k just for headers to fit a 351 in a 94-95 body. So far kooks is the only company that I have seen make them.

It's a great deal, but the kind of application I'm talking about leans towards EFI and hydraulic roller.

There's a lot of good info flying around here.

buy his motor like it is

sell the carb setup and you have enough to buy a decent intake like a systemax or something comparable.


dont knock the 331's...i just saw one make 421rwhp......

who's knocking them?

Remember this thread was just about mulling over the cost differences between the 8.2 and 9.5 routes ... not really about what I necessarily plan on doing. (not to mention I don't have 4 grand in my back pocket to spend all at once either)

Truth be told I was trying to hammer out ideas about whether to do a simple 302 h/c/i or move up to a mild-mannered stroker setup and someone suggested just ditching the 8.2 and move up to a 351w based engine since "you'd be replacing everything anyway". That's where the question of cost pros/cons came in.

Tommy's point about swap headers for sn95's was something I hadn't considered and would play a big part in the final cost of a swap.

when i did my 94 with the windsor i did try 4 different sets of headers and wound up getting the kooks headers.2 years ago the cost was like 980 shipped

[natedawgg94]

would you need the kooks even going with a tubed k-member setup?

Jon. Have you ever driven a stout 331 or 347 streetcar?

You'll keep the sleeper image, and alot of parts you already have by sticking to an 8.2 deck motor. And it will be plenty.
