Yes something in that area, I do have a OE roller block though. Im sorting through some now.. Really dont want to spend 300 on it.

Does the milling of the heads effect what pushrod length I require?
I plan on shifting this thing around 5200 on weekends. Is that a problem? friends say no, just wondering if I should install arp rod bolts while the oil pan is off.

Disregard shift point question im going to assume it's okay lol.. I have never owned a 350 so wasent sure about rpm range, at 3200 my 3.8l v6 sounded like a rc car motor.

The cam is a good selection, I like Howards Cams. It is too late to replace rod bolts now. Usually you replace rod bolts then have rods checked and resized when everything is at the machine shop.

Now that cam selection is out of the way, Ive been looking at steel skip white full roller rockers. does anyone have experience with them? The price seems pretty low.. Im sure the "lifetime warranty" only covers if they break in half or something but still seems like a good deal.

My vortec heads have guide plates and screw in studs. I need to be looking at narrow body rockers right?

Im still looking for a couple more opinions
I was under the impression that I would need to change my valve springs

135 lbs. @ 1.750, 325 lbs @ 1.200 (1.250 diameter) sais good for .600 lift cam.


I can use my .500 lift cam with these springs? I assume they are for a roller cam as they are on vortecs?

I would use what you already have. Why would you buy a different set of pistons for a little bit more compresson? Then you are going to have to get new pistons pressed onto the rods. You might not even notice the difference in the performance. You can buy a used roller cam on Ebay, they are reuseable. If you don't want what you already have sell it. It might not be easy to sell and then you will have to find something else.

How much is all that going to cost? You will turn a $400 dollar short block into something that cost thousands.

Yes I am leaving the short block as it is. Except for the stock flat tappet cam.
Im sure there was A cheaper way of doing this but it is what it is. Im looking at 1600 for the long block. I need to buy Roller rockers next and am looking for anyone that has exp with skip whites steel rockers. Or is there some nice GM rockers I can use? My vortecs have guide plates installed.

You could probably buy a used late model LS engine and buy the aftermarket intake for a 4 bbl carb on what you are trying to do to a $400 shortblock. That shortblock was not a bad deal as long as you don't end up spending a lot of money to make it work.
