What is everyone doing about the brake booster for the power brakes? My new motor has a lot of cam in it and was looking into a electric vacuum pump to help with the brakes. Could I run a vacuum canister from the motor and then plum it back to the stock booster or would that still not be enough?

Alright here is my question. When swapping a sbc into a lt1 car what wiring do you get rid of and what do you keep for all your lights and such?

The lights are ran off of the BCM and the motor is ran through the PCM so you basically take the harness that is hooked to the motor and the computer under the hood out and all your lights (headlights, turn signals ect) all work fine. The only wires that you will have to trace from the stock harness are the reverse light and the wiring for the stock key switch if you choose to have it start off the key

Is that the lt1 350? And what did you put it in? Any conversions or problems?

sorry for late response. Its a 1970 350. Install was pretty straight forward. Just bolt in the rear two bolts on the block to the stock motor mounts. everything else bolted right on

Default Radiator Question

Firstly, my car is track only. No a/c, no PS, no belts, no windshield wipers, etc. So please don't hammer me with the, "why didn't you use a LS motor stuff." It's a 98 Camaro that's been converted from v6 to Gen 1 SBC carb'd. We've done it right with BMR stuff. The radiator is posing a bit of a problem though. Does anyone have insight into using a LS1 radiator with my setup or where to find a radiator that isn't too tall? We can fab one in, but hey, if we can bolt one in it, that's always better.

Yep, bought mine from Amazon, they fit perfectly!!! The price ain't too bad either. They're Pace Setter 70-2239 Painted Long Tube Exhaust Header. Just search that in Amazon and you should find them.

Default now this is what iv done so far

Took out the 3.4 and t5 put a lt1 engine cradle in.. Now I'm thinking about the th350. Now what driveshaft do I use and can I keep the v6 rear end and what about the v6 fuel pump. Also the speedo? I want to custom my dash and put all after markets in.. The speedo is the only I need help with. Also what rad? What Altinator/power stearing set up did you use.

I got a lot of info from here but over time many of you completed this so I know you guys have figured out easier ways
