How big of a nitrous shot could my new fordracing long block with b303 cam, Gt40x heads, edelbrock rpm air gap intake, 625 road demon carb, 1.7 roller rockers, hooker super comp headers,and flotech exhaustbe able to handle safely ???? It uses the production short block 9.0:1 compression flat top pistons.</P>

what kind or pistons,rods,rings?

Safe would be anywhere between 100-125. More important is to tune to the plugs. If all looks well go up to 150.

I differ on this one it could go 250 on this one...just need more info what intake
I just put a 250 shot on a 350 in a 70 nova
it's a stock block,steel crank,pink rods the forged flat tops,strip dominator intake with a 750 dp holley<img border="0" src=smileys/smiley3.gif border="0">

stang574 sound right if it were an otherwise stock motor with the hyperuetectic (however you spell it) pistons. Forged pistons, depending on quality, should probably be good for upwards of 300+ hp, so long as the motor is in good tune.

The motor made 370 horsepower and 358 lb-ft without the 1.7s, edelbrock rpm air gap intake, and hooker super comp headers. It is a stock production short block minues those bolt ons. So ya its got the flat top hyperutectic pistons 9.0:1 compression same as a stock 5.0 I would never go past 150 on a stock block thats for sure

You want me to rebuild my motor with a 347 already lol 250 shot is way to much for stock pistons. 250 is a good number for forged pistons. I'm lucky i know a little bit about engines. Your gunna tell some person that and there gunna blow there motor lol</P>

mdvaldosta

he said he put 250 on forged pistons, and also we didnt know if yours were forged or not. Ford used forged pistons stock in mustangs until 1992.</P>

T5..you might know engines but reading isn't your strong suit...that's why I asked about pistons etc..I have built 100's of engine and no I'm not looking for a pissing contest....any dumby can say put a 100 shot on it...the guy ask what is the most and be safe....on more info from him I could get him the info..would I use a 250 of a ford pistons no....if he has a dual plane intake I would again say NO to 250..carb set ups as different from the injected car....no that's not in any magazine either. <img border="0" src=smileys/smiley14.gif border="0">
