......and i am wondering what would be the best choice of piston cc to go with a for an N/A application, would like to have my CR to be around 9.5 or so. Any suggestions, and oh yea the heads will be my ported PI heads. standard gasket width too.

If your going to do a stroker and spend all that money I would say you should at the very least go with 10-10.5 to 1 compression. You can still use 92-93 octane fuel with that compression but get more power out of it..and why not build it for a blower? Those mod motors struggle without boost or nitrous. What say you

[Intmdtr]

well thats why i was looking at a lower compression so that in the future i could add a blower....am i not right in thinking this way?

[armyed]

no you are absolutely correct in your thinking. I just saw your post where it said it was for an N/A application. The best compression for a blown street car is anwhere from 8.5-1 to 9.2-1 or so. But the wonderful thing about head gaskets are you can go thicker and drop your compression down. Take for instance my dart stroker motor, It has flat top pistons and my compression is going to be around 9.1-1 compression with a thicker cometic gasket with studs to hold the heads down. But if I went with a thinner gasket I can jump back up to 11-1 compression take the blower off and throw Nitrous on it. It's all about having a versatile motor. So for you if you got a flat top piston that would put you at 10-1 compression and a year from now bought a blower, take your heads off put a Thick cometic gasket on it and your ready to roll.

cool, ya i knew about the head gaskets and such. right now my compression is 10.1.

just not sure what size dish to go with in a stroker to achieve the 9.5 CR

Just ask the people who make the short block, tell them you have stock heads that are just ported and they will tell you what there setup will make with stock cc heads and a stock thickness gasket.

i suppose, i need to get this GT moving a bit quicker, hopefully 13's next year.

I hear you on that dude, its a never ending mission, You will get 350hp and you will drive it for a week and it will feel slow, then you will get a blower and get 450 and you will drive it and it will feel like the fastest thing in the world, then a week later it will feel slow..see where im heading with this....hahaha I have been going through this for a while now..hahaha now im looking for 600 with a shit load of torque.

[Intmdtr]

i did that with my 93 GT, starting with the 5.0 then dropped a 351 and some nos into it.

[armyed]

Hahaha so you know. That shit just never ends. I can see it now, a year from now ill be hitting 1000 with a YSI trim because 600 got boring...lmao its a never ending money pit but I love the shit.
