procharger newb few questions recently purchased procharger d1 for my 98 camaro it is currently setup with ms3 and stage 2.5 5.3L heads and stock bottom end.
are these heads ok for f/i application?
what camshaft do you reccomend?
rod bolts and head studs any other suggestions?
how many pounds is safe?
what size injectors ?
is a racetronix walbro fuel pump w/hotwire kit enough?
any feedback greatly appreciated thanks

The heads will be alright. Id go with the EPP blower cam if you really want to do a cam swap. Id run about 8lbs on that setup and 60lb injectors will get you there. The Racetronix kit with hot wire kit will be good, but not much after that.

What exhaust are you running? The more free flowing the exhaust the less boost you will net. Is your motor forged? What are you power goals. These are all things to consider when going FI. I had to learn the hard way thats why I am asking.

i have hooker longtubes off road y pipe and magnaflow cat back, stock bottom end, i would like to see 550 not sure if this is realistic with stock bottom end
If you're considering upgrading the rods and rod bolts, do the pistons as well. Pointless to have one without the other. Once you have those in place you can REALLY turn up the boost.

With 8 psi and our cam, you can see 550 rwhp with a stock bottom end. Bob

I'd look into different heads. Your compression is pretty high right now as is for FI- especially on the stock bottom end. Get some cheap 317 or 035 heads from a 6.0L.

For your HP goals, ported would not be necessary. I would however use better springs for sure. I'd have to do the math to give you an exact answer, but IIRC the 71.5cc chambers of the 6.0L heads would give a stock LS1 a compression of something like 9.5 or so.
