Default New D1SC with Forged 347, How much HP on 91'?

Hi guys,

I just purchased a D1SC kit from SoCal.. This is what I am looking for.

I have decided I am going to rebuild the engine before I put it on (same time)

Going to do Compstar rods, and diamond forged pistons. Probably going to have to get a set of Oakley Sunglasses too....

Now that your laughing, my question is this. I Really would like to run a Single F/P, I do not want to run twins and have to modify it... And I want to run on pump gas, 91'...

The kit I bought comes with a 3.7" Pulley and a SDCE 7.25" crank.

My question is this, what kind of fuel system will I need? Considering I only want to run pump gas (91'). And how much HP/Boost will I be looking at with the 3.7"? Or since I am running pump gas I need to run something bigger? Or smaller?

Yes there are single pumps that can handle your setup. On 91 I would guess 625-650rwhp with that pulley combination. I think you will be at 14# which is fine on a built motor.

Do you have suggestions on what F/P to run?

I run RSI's twin in-tank setup, but I would call A&A or EPP for a single pump setup if you want it.

I don't think RSI makes a twin for the F-bodies?

I am thinking about purchasing a LS6 cam, and LS6 springs..

Will that work well with 13-14#'s?

And also what pistons do I need to run? I am going to run the stock heads, maybe get a set of 241 heads since I have 853.. But still pretty stock heads
