Good idea or bad idea??

flamed 98 gt · March 1st, 2009, 05:29 PM

To stroke out a stock 302 or get a different block? Was think about a 331 or a 347. Not sure if the factory block would hold up with it stroked and sprayed.

people do it everyday, anything over 500hp and they say you are sitting on a ticking time bomb

89LX347 · March 1st, 2009, 05:57 PM

do what you want. either way, one of these days, you will get a different bock.

Racinjason81 · March 1st, 2009, 06:17 PM

you can build a 347 stroker and make 500hp N/A so who needs spray.If you want more power you could do a 351 and have extra cubes and a stronger block.

Ok if I did a 351 (factory block) what will it hold before it cracks?

89LX347 · March 1st, 2009, 09:38 PM

AROUND 700 hp. give or take a few hundred, depending on how its built. 69 blocks are the strongest ones

well using a stock block would save $$$.... but: "Cheap, Fast, Reliable....Pick 2!"

Use a 351 over a 302 anyday IMO.

What kind of block are you running?

89LX347 · March 1st, 2009, 11:55 PM

I have a 351 clev making right at 700 hp on motor to the fly wheel then spraying another 300 BUT!!! I've been through 2 of them all ready so its a bit on the edge. people say a 347 stroker at around 500 hp will split down the middle over time so its a toss up

You are making 700hp to the wheels with a naturally aspirated 351 Cleveland? I think whoever you bought the engine from is pumping you full of shit. You do realize that is about 900hp at the flywheel, right? And then you are spraying 300hp on top of that 900hp.....with a Cleveland block. What kind of car is this in and what does it run? I'd love to see some pictures of this 900hp n/a 351C.

chriswao · April 17th, 2009, 12:43 PM

sorry darrell my mistake not to the rw but to the fly wheel trying to typ fast at work and wasnt thinking. But I will get some pics on here O and its in a 89 hatch

88Saleen · April 17th, 2009, 12:56 PM

now if he goes with the 351 what else would he haveto swap out? motor mounts, headers, computer... seems like maybe you can build a decent 331 n/a and keep it around 400hp and the stock block should hold up. dunno just my .02 $

chriswao · April 17th, 2009, 01:04 PM

also trans and or bell housing

88Saleen · April 17th, 2009, 01:13 PM
