I looking into building a motor for my 02 Camaro. The goal for the motor is to have a Whipple 2.9 super charger on it. I would like the largest displacement I can safely achieve. I looking into the LQ4 because they are fairly common and afforable compared to the LS2/3.

Any input would be appreciated.

Because you are going with a blower. Bore it .030 and put a 3.900 crank in it. It will let you put a good piston in the bore for boost and give some stability when the piston hits BDC compared to using a 4.000 stroke.

It will net you a 390 cube motor this is the motor AES racing makes in their 390 setup.

You won't notice a few extra cubes here and there, especially now with a 2.9 whipple on top.

On a high strung N/A application sure you might see a bit more torque in a 408 vs. 364, but with all that insta-boost from the twin screw you won't miss the extra torque down low that a bigger cube motor might make.

Like silverbullet said before, a 390 is probably your best bet if you really care about the cubes. Although depending on how much boost you plan on pushing though this you might even be better off with a smaller setup like a 366-370.

If you plan to boost the motor, I would not go more than 4.030" bore and 4.000" stroke. Those AES 390 boost short blocks are sweet.

I find it very difficult to curb my bigger is better addiction, although my budget does.

I was not familure with the AES option. Great info I'll give it a long hard look.

Thanks.

Sonic testing will determine the bore.

Stroke, anything more than 4" and you start having skirt wear. But you can go 4.250

Put the wrong piston in a motor and boost it and you will find your cure and your wallet will be flat

You probably got that from your wife. LOL

Yeah, but I saw a chick a couple of days ago with a T-shirt with a new twist:
It's not the size of the boat or the motion of the ocean...but whether or not the captain can stay in port long enough for the passenger to get off".
