It is very hard to make a streetable 600hp NA 350. You will either need to stroke it or add some sort of power adder to get that kind of number. I will move this to the carb section for you but they may choose to lock it since your motives are a bit scewed.

Look for a thread titled something like "lets talk about 500 hp N/A builds" or something like that. you will see that while high hp engines ARE possible out of a 350, you lose pretty much all street manners.

You want a 600 hp N/A? Go build an SB2.

I have seen what TT Supras can do. you wont beat him without a power adder, biger cubes, etc.

possible? well of course everything is

streetable? i'd put my money on no

likely? if you got pockets deep enough

if i were you i'd go with either a BBC or a 383 stroker and try something from there, but without a power adder or lots of cubes 600 hp is a tough number to get to. and if you get to 400 or 500 and aren't happy just strap on some giggle gas and call it a day.

Getting above 500hp in a 350 is going to take some exotic parts - not to mention precise machine work so the puppy stays together at 7500rpm. It would be a lot smarter to build a bulletproof 400hp 350 and then add 200hp nitrous. It would also be a lot cheaper and 100% streetable.

My uncle was a state legislator. That doesn't mean I knew what was passed into law.

"600 HP NA 350" and "streetable" don't belong in the same sentence.

i never said it was streetable

i'm not here to argue, its the not the point of the board, but I will believe my uncle who helps build Nascar truck racing engines for a living over anyone here who wants to challenge the HP rating they make

And not one bit streetable!

...as long as he tears the supra up on the track

I don't see why you'd want to stay NA; just get your own TT setup.

I have to agree with the "unstreetable" claim. I am getting almost 600 out of my 327 (12.5:1 pistons), there is no muffler that will quiet it and it is a pain to try to drive it anything under like 60 mph. I have now gone to 5:60 gears with a 5000 stall converter...maybe this will help the thing drive down a residential street.
Upside is that it can be done and it sure gets attention!

As the quote goes "Whats the similarities between a 500HP supra and a 1200HP supra? --- THEY BOTH RUN 12s"

Chances are this 600HP supra is just a dyno queen like most other supras.
