I've seen a guy run a Miniram on a big SBC. It was stock block, he ventilated a cylinder wall (no hard blok). Track-only car.

He's running faster now with a single 4bbl on a smaller displacement SBC (413 - 406, IIRC). Motown block.

i think it would be really sweet to have a 400+ ci motor with EFI. you cant do this to LT1's beacuse no one makes a 400 LT1. if i get a TPI vette, im gonna do a 400+ build with an aftermarket intake. it would sound so sweet too!
