Thread: 350 build bottleneck???

Tweet

I'm sorry, but this reads like a magazine rebuild. First, what is the intended use of the engine? 4/7 cam swaps have NO value in street driven engines. Any benefit they show is usually above 7000 RPM.
What is the compression ratio, as a guess, I'd put it at about 8-1 UGH!!

\What is the duration of the cam?? It appears to be WAY TOO MUCH CAM for an 8-1 motor. Is this a street driver, street/strip or strip only car??

I wouldn't do ANYTHING until these basic questions and needs were addressed.

I have built many motors of all different sizes, and have never killed a cam !! and after reading all this crap. I'm confused! To much about nothing

I use farm tractor or Diesel grade oil, it has zink in it, there are others also, I use to break in my motors, (1st 3-500 miles on a street motor) then you can switch to synthetic. And use light valve springs & stock rockers till the cam & lifters are broke in.

Google flat tappet breakin and you'll find many more oils to use, and a lot better info!!!!!!!
