If you build to please someone else, you may never be happy.

You wont get the "most power" from a donkey dick cam. You will get it from the proper cam.

You will need an upgraded fuel pump and injectors and a new oil pump and chain if you are going to wring it out hard.
The truck maf can help, but we also have a custom 4" kit with a card style maf that will work well beyond the truck maf's capabilities.

And we offer the option for custom tunes etc. You will likely need alot better idea than just "gears". That 10 bolt wont hold up long. If you use a rear end girdle and HD gears MAYBE. But still borrowed time.

Next up is the clutch. You will need a rather harsh clutch for a single disc OR you can go with the mcleod twin disc RST and be golden for anything you do to the stock LS1.

dont forget 160* t stat

And ditch the alum driveshaft. It will likely wad up when you launch under too much power.

Then you will be looking at suspension. You should prob do suspension in conjunction with all of that really. In the rear at least.

I would go with the 12 bolt. We have a good price on them. But everyone else will sway you toward the 9". But remember, the 9" will eat up more power....so there goes the idea of this thread too...

Absolutely . . . Heads can be gotten completely assembled and ready to install !

STRANGE S60 with S-TRAC Differential, which has a lifetime warranty !

STRANGE also has custom Chrome-Moly driveshafts for just a shade over $300 !

AI or TFS are still the better 2 options on a 408.

We have sold a few S60s lately. Some people do not like the limited gear selection, but who would want to go under a 3.73 anyway? Ha.

Torquer v2 would be a nice cam for this setup with 3.90 gears. By the way, check out the Strange 60 rear, good settlement for a strip/street car.
