Default 87 IROC 5.3/w th350 budget build

Well where to start? So about 5 yrs. ago I bought this car and have basically put it on the back burner for the last 4 of 5 years. My original goal for this car was a turbo 6.0 with a t-56 behind it. But things, or should I say finances have given me the chance to put some money and time into the car.

So about a month ago I called a friend of mine and he got me into a complete 5.3 with ecu, harness for cheap so I jumped on it. Then I talked to another friend of mine had some parts for sale. LS6 intake, 42# injectors, psi valve springs, corvette water pump and idler pulley, throttle body, billet fuel rails. So then I came on here and tried to find a ls6 cam for cheap in the classifieds. I ended up with a 98 ls1 cam for $40. 500 lift with a good lsa for some spray hehe. This was the plan with the NO2, because I was just gonna slam this thing together and make it a runner asap. Things have changed, and I am looking to be running the 5.3 with the truck manifold setup. Now I haven't heard of anyone doing this in a 3rd gen yet but I'm sure someone has done it or has input on this setup.

So over the next 6 months I should be able to get this build done I hope in all my spare time. I will be posting pics but have to learn how first. So for now wish me luck, and I will keep you all as up to date as I can.

One of the things that I am not set on is the use of the th350 that I have. I would really like to run a t-56. But I already have the th350 and its set up for a camaro with a torque arm. What do you guys think auto or manual?

You havent been on TGO yet. About 1/3 of the swaps use a LM7 and a few kept the truck intake. It's so tall you need a cowl hood and even then, the alt usually hits. Id use the LS6 intake and sell the 42lb's for something smaller

T56's are still expensive compared to TH350's, but the TH350 will work using the crank adapter
