If you want a great cam with a decent budget, you can send the stock cam to Delta Camshaft in Tacoma, Wa and they will regrind it to whatever spec you want. They have been doing it forever. Just call them and tell them what you are doing and what you want out of it and they will recommend a grind and do it for you. My l29 roller cam was $140 shipped and I had it back in less than 2 weeks from when I mailed it out.

This is a great budget build! I went through Texas Speed for my 224R Cam and valvetrain etc. Engine came from LKQ Online. How many miles does your LQ4 have on it? It’s interesting you did this spreadsheet. It’s literally almost identical to the one I made to keep track of parts needed/bought and prices and vendors lol

Not sure How Many miles on the LQ4, I will update when I check the ECM
Think I might try a summit truck cam. I do plan o putting a turbo on the motor it will receive an HX35 with a V-band Hot side from Turbo Labs of America.
