Did you have to mod the frame to make this engine fit or just did you just get the Motor mounts from BRP and use a different oil pan?

IF you wanted to add an AC system, Would it be possible?

Yes, the ac compressor sits low on the passenger side of the motor.

No mods to the frame just drilled new holes in the crossmember. The oil pan is from Holley, I found a cheaper pan at Jegs that will work it's a GM performance parts piece.

The 4.8 and 5.3 are the same block, 4.8 has a short stroke crank. I purchased the ARP head studs from Summit, they were on back order for a while. I have a set at the shop Ill grab the part number tomorrow and post it up.

We are going to tune the car on E85, looking for 700-800 rwhp running mid 20's on the boost

The short block is stock except for arp rod bolts and head studs. We disassembled the motor cleaned everything and opened up the ring gaps to .028. Again this is a $250 junkyard motor.

Are you using new rings and setting gap to .028 or are you just reusing the used stock rings and setting gap to .028? Thanks

Where did you get the parts for the corvette accessorys and did you change the harmonic balancer? i am very interested in the numbers on this motor. i think it is going to be impressive to say the least..good luck......Bob

you will not need that much boost to make only 700-800 rwhp. I did that on 11 psi with a set of twin 62s
