Thats a lot of drivetrain for a 4.8...have a particular goal in mind?

5.30's... its an 1/8 only car. ive seen several gen3 motors run 5.5x's with relatively weak 60's and i plant to be in the .20's for that ET Goal. I honestly dont think it will be an issue with the gen4 4.8

This will also be on a radial. Radials are faster as long as you have the suspension for them.

Awesome car man! I like those mailbus. Guy I know had one with a 460bbc that was badass.

Sweet project! I thought the 853's had issues sealing with the LS9 gaskets though? Or was it a different older casting #?

im not sure... i am likely going to runn 243 or 799 heads. I copy and pasted this from ls1tech when i planned it a few months ago and a few things have changed lol.

Oh another thing. I run the 4303 as my secondary pump in my Vette. I'd suggest at min a 40A relay, 8ga wire and a bigger auto style fuse holder to keep it happy.

Nice build! I am looking at going with that same intercooler. How does the quality look in person?
