5. I used Sanderson shorty headers that have 1 7/8 primaries and 3" collectors. I know this might sound small, but think about it.. what sense does it make to use 2" or 2.25" primaries when you neck them down to 3" exhaust anyway?

Curious if you scaled the car. What was the percentage in the front end if you did?
The diff between a BB & SB is about 200 lbs, given you have cast iron heads on the BB. If you moved the engine back some, the additional weight would be negligible, given the weight displacement (front end percentage).

I get easily lost with the computer stuff but I don't doubt Mr. Jamison who appears to know a little about Corvettes.
And yes I'm having problems with my 89 since I removed the air pump. I suspect it's related to fuel but I'm not discounting an ECM problem related to the air pump being removed.
BTW, Tony I can't believe all the time you put into this project and taking this on all by yourself. My hat is off to you and your beautiful and also incredibly powerful car. Why do people climb mountains? Same reason you did this. Truly amazing. Kudos again.

I don't think a big block with aluminum heads weighs that much more than the aluminum LT-5 motor and I heard they used those in the Vettes at one time. Go for it, tons of torque and power. If you want to reduce some weight bore it out even more. You have to notch the k member if you want to use a regular oil pan and motor mounts. You can also use the a/c box off of the LT-5 car I mentioned earlier to give you more clearance around the valve covers.
Try getting the sound of the new Z06 out of a small block's internals, the 4.125" bore and 4" stroke of the newer LS7 are the same as the old BBC 427 internal dimensions except they seem really expensive yet and there is room to grow in the bbc block.

This is a low 10-second daily driver in Chicago traffic owned by Kevin Costello of Chicago. Guy in the video is Pete P, one of the "FBI" gang that built this stroked and sleeved 441 inch N/A LT5. Other significant mod is the ZF was replaced with a 4L65E and TC lock. Perfectly drivable manners in heavy traffic, cruises to the track, changes to slicks and runs in the low 10s!

I'm here.. still have the car and have been driving the heck out of it. The car sat for a few years, and then I rebuilt the motor last year, made some larger headers, figured out the cooling issues, and added another blow off valve. My 15 year old son and I love cruising in it. We just took it to a car show tonight on Noblesville, Indiana. Had an awesome time! I hope you all are well!!!!!
