Cant get 500rwhp n/a with that kind of money big hp cost big money unless you use some spray that will give you the hp and tq you are after. But a 500rwhp h/c ls1 is going to cost some money and need some custom parts.

yea i figured, im just tryn to find some cheap used heads with the correct cc to help get me their. putting price aside, you know what heads would help get their? im already going to do injectors, but without heads i dont want to buy to small of lb injectors. if i ran it with stock heads, 36-37lbs would be enough but heads will change that

afr, tfs, prc heads are all able to hit that number but you would most likely need a different cam to match the heads. You want to have your cam match your heads not the other way around. If i were you i would call tsp since its there cam they should be able to set you up with the best heads for that cam and your goals.

Custom Cam and some AFR/TFS is your best bet dude. And a good set of LT's ( I'm guessing 1 7/8 ) unless you have 'em already.

I was informed that the ms4 either has to be used with stock chamber heads or the pistons have to be fly cut. I have a set of dart 205's I asked a member about and that was the cam he chose to run with the set he was selling.

I dont remember what size the chambers are on the 205's but I know it makes the compression go from 10.0 to 10.8 to me thats a pretty big difference not counting they flow a lot better than the stock heads.

Kooks has 2" primary headers which may free up a few hp if your trying to find the most out of exhaust. I went with the cheapest I found but im not after numbers just better than stock.


There was someone who had a 2000 z that drag races that advised me there were better cams than the ms series. I cant remember what brand/ place to purchase from that he suggested but hes running 10's on stock heads with the upgraded springs. I can try to find out if you might be interested in looking at other cams that might perform a little better.

I looked it up, the darts are 62cc.

You can find a used set of heads complete for around $1,000 if your looking. I paid $650 for new bare heads that I will have to spend a lot to put together.

yea im open to options, only reason im running the MS4 is because i took it out of my ws.6 and since i had the cam rods and springs in the stock heads of the car i figure why not swap the same set up in my ss for little to no money. ms4 is a mean cam and is open to make big power, also a spray loving cam too but im after n/a

500 rwhp will cost at lest $4000 when done.get some PRC heads from TSP,215-227 cnc .get a PAT-G custom cam,you should read his sticky thread on this topic.get a used fast 92mm combo.you will need a bigger fuel pump and injectors.you will need a better clutch ,and the stock rear end won't last long at this power level.power/speed cost.

well i have a ton of parts already so thats why im lookn for just heads, tsp says MS4 can be a 500+ hp cam

parts i have:
MS4
Valve Springs
Rods
McLeod Street Twin Alumin. Fly Wheel
Fast 92 Ported and Painted by Ron at Vengeance
Nick Williams 92
Lid
QTP
True Duals
ASP Pully
Stock Rear with 4:10 and Auburn Posi Dif(will hold aslong as i dont put slicks on for a little while)

need heads and injectors, cant choose injector size with ouy knowing what cc heads im going with, so 4000.00 isnt how much i need to spend

can anyone steer my toward head size and brand even to get close to say 480ish wheel, i kno of cartec set ups with smalllllll cams (224ish) that make 440+ wheel with unported fast 90's. i kno some ones guna say big cams dont make big power but they have alot more room to play with hp ratings.

Off topic question, sort of. But, why is the peak rwhp of 500 important and not just a really well performing car?

why would the cc of the heads affect your injector decesion? cc just affects compression ratio not as much horsepower. id say 42# would be fine for your setup.
