i dont know my car is pretty much stock like i said before i will be camming it but nothing big the the brightest when it comes to specs of stuff more a body guy my self as for the studs 3/8 as thats stock right?
3/8 is stock is yes.
I say go 7/16's.
1) Because studs are cheap
2) Because it doesnt change the cost of the rocker arm much, if at all usually.
3) Because valvetrain ridgidity is always a good thing regardless of the level of the build.
4) If you buy a quality lifetime-warrantied rocker, you can use them on a possible future build that would "need" them.

^agreed! Buy something you can use down the road. Sa rockers are for bolton cars only imo. Nsa rockers w/ 7/16 studs should be mandatory for heads/ cam setups. If you can afford it, get the comp high tech stainless. This rocker will most likely outlive the car.

you will need to click on small block chevy and it will give you part numbers for all the ratios for 3/8 and 7/16. unless you have had the heads worked to accomodate a higher lift i would not go over 1.5 ratio. you can go 1.6, i have seen it done, but depending on whom you speak with the stock springs (even on a stock cam) are being maxed out or dangerously close if you go with 1.6.

I got springs CC Springs and CC puchrods NIB I let go for 100.00 Shipped.
I bought some TFS heads and wont need them. Also got some ls7 lifters which in my case require a slightly longer pushrod.

ok so i have decided like posted above that the motor i have now is gonna stay mostly all bolt ons and im going to be building a 383 on the side for now i want a set of rollers rockers for the bolt on motor so 1.5 3/8 good idea?
no because you will have to sell those and buy nsa 7/16 for the 383. Buy the right rockers the first time imo. Get a set of 7/16 nsa 1.6's w/ upgraded springs now and transplant them onto your 383 when it's built.

well im building an entirely diffrent motor on the side the motor in the car will stay how it is minus some things but the new motor will be w whole diffrent block (dart block) so im building a street motor and a whole diffrent race motor on the side so for the bolt on street motor good to go with the 1.5s?

1.5s are fine because they are the stock ratio anyway. if you dont plan on using them for another build then it might not be a great investment. 1.6s would have a greater resale value if/when you part out the current motor.

Sounds like a waste of money to me if your building a 383.
Why not buy something once and just switch it over when you do the swap. I recommend the Comp High Tech Stainless rockers as well. Also 1.5s are a complete waste of money on either set up IMO.
