want to get in high 11's

[shadowsdaddy]

i have an 87 limited with the 307, just purchased a 83 turbo v-6 block which i plan on sleeving all 6 cyl on, girdling the mains, and stud gi0rdles to keep valvetrain in line, plan on using 9:1 comp. forged pistons, 87 heads with a real good porting and polishing, comp k cam setup and an 85 hotair intake with turbo with adjustable wastegate and an intercooler, can anyone tell me what et times this would be good for i also need help picking aftermarket injectors- what size, i am also porting the intake to match heads, any input would be good

If you're starting from scratch, and doing that much work on the motor, and plan on going the intercooled route anyways, why use a hotair intake setup? If you do all you listed, but with an intercooled intake/turbo setup, youd be able to hit your goal very easily, and then some. It can definitely be done with a hotair setup too, but it will be a lot more work, and may cost you more in the end. Not trying to do any hotair bashing, I have one and love it, but if youre starting from scratch, and want to use an intercooler anyways, i dont see why youd go with the hotair setup.

If you have your heart set on it though, go for it, and build the car that makes you happy... youre the one who'll be driving it, not me or anyone else As far as injectors go, I've seen a lot of knowledgeable guys on here lately recommend going with the 60lb'ers. Unless youre building a balls out strip car they should be able to handle your needs, and with modern chips theres no real driveability issues. That way you'll only have to buy injectors once, rather than buying a smaller set and maybe needing to upgrade later as you get faster. My car is pretty much stock though, and I am by NO means an expert on GN's, so im just passing along what I've been reading here lately. If anyone else chimes in to correct me, its probably better to trust them Hopefully some of the more knowledgeable guys on here will chime in and give you some better answers

i wouldnt sleeve all the cylinders ,measure them all then see what you need
sleeves can move with enuff pressure or block twist
any block will work really.
and if your going to sleeve all cylinders ,bore it out to a 252
