Default RE: how much power can a 351w block take

thanks for all the info i don't really want to blow my motor but if it happens it happens as long as it after some use and i have enuff money saved up for a dart block or man of war block. and i figure i would just run the t-5 untill it gose boom i just rebulit it less then 1k ago. i just hope i can make it this whole summer at least runing around 500-550 horse all of the time well not when i'm cursing because the sweet thing about turbos is if you don't get on the gas you don't hit boost

I think they are 'safe' to about 600-625 unless Dick Sherman gets near it with a lot of high-dollar stuff and then it can make 750+ -----ALL MOTOR.......

get a g force, not a tremec. a tremec is notchy kinda ruff shifting. but a g force wines a lil. so take your pic. or you can go with a t-56 viper trans thats going in mine.
not true. the new TKO600s are a the best on the market by far.

The new style TKOs' are great as long as you don't have to shift just above 6500 rpm's. They don't want to shift in that range.

My Brother in Law has a 351 stroker that dynoed at 850 HP. It has a girdle, and the block is partial filled. Above that, you need a after market block.

yeah,cause a tremec wasn't designed for the weak wristed...

my tko is notchy on street duty,but racing it's smooth as butter.
remember the 351 w is a 302 block.

the block is your weak link.

Most people say to go with Dart block
over 500 hp.


You can probably get by for a while
but dont be surprised if it comes apart on
you one day.
Thats with a 302 block. A 351W block is much stronger than a 302 block. A 351W could very easily support 500hp and if its a block from 74 and under its alot stronger also.

I also talked to a guy before who ran 800hp on a stock 351W block with a girdle (the girdle doesnt do much though) but it will sometimes handle that much power but when your pushing that much through that block its just a matter of time.
