Ok gents, im am about to start my build but a couple of questions. I

 

OOPS hit send on accident.questions below.

1. Do i need to send the clevite main bearings to the machine shop when i send my block and 4.2 ltr crank to get honed and mounted and balanced?

2. Will i be able to put a 1998-2001 model head on a 1990 renix block.

There are alot of things that i have researched already and do actually have a decent understanding of but having some input from those of you that have already swam the waters is priceless. I have also played around with the idea of having someone machine a roller cam even though that will be like $500 to $1000 from what i've read.

I will be posting pics soon. I do plan on this being pic intensive. Will be doing all kinds of things while waiting on the engine work to be completed.

One more thing..... I was told that if i do manage to make my engine a complete roller system i would have vaccum problems. This is one thing i dont have a decent understanding of, my ears are open gents to all sorts of info, even from the bitter members!
