power.
So the new motor has 4000 miles on it and it is starting to feel slow again.

I am debating and looking for opinions.
Right now I have a 370 (LQ4) with 230/232 .613/.598 (Pred Z cam), PRC 5.3 stage 2.5 heads, LS6 intake, LT's, 3"true duals, UDP, ETC running 12:1 compression.

I am debating going with L92 heads, different (bigger, more aggressive) cam, and LS3 intake, offsetting the cost by selling my heads, intake and cam. Would this be a worthwhile swap as far as $$$$/power ratio?

Other idea is swapping heads to lower my compression and adding a procharger, obviously costing MUCH more.

Or any othere ideas. NO2 is not an option.


Please voice opinions.

Do a stroker over 400ci and get l92 heads with a bigger cam

Why is N2o "not an option"? For money invested vs. amount gained it is a very viable option.

Wouldn't I still have to swap heads to lower my compression with NO2 as 12:1seems high for NO2? If I go with a power adder it would be a procharger/turbo so the power is always there and not have to worry about bottles/etc. I have nothing against it, just seems like a hassle to me. The nearest refilling place is 50 miles away also.


The 400+ stroker route is the route I wished I had gone, but funds limited my unexpected 370 build. It was a build that started out just heads/cam LS1 until we found bad cam bearings in the LS1 and it went down hill from there as the LQ4 block I got had a scored cylinder wall, hence where the 370 came from. At the time using the stock crank, LS2 rods and Diamond pistons seemd the best bang for the buck route as I had not planned for a complete rebuild.

In all honesty, with the stroker at this point, I would sell my 370 and then buy a complete long block and not worry about reusing my block. I guess I will need to get dyno graphs/numbers so hopefully make the sale easier.

I would prefer to get back to an aluminum block also, but not a big issue if I don't. Now the Procharger is looking cheaper.

IDK-I had so many issues with the unexpected last build, I am "gun shy" I guess and want to make sure I do it right this time.


Looking for serious options to get me at/over the 500rwhp mark. I am very confident that I am solid into the 450rwhp range now.

The great thing about the procharger is it'll get you to 500rwhp and you still have room to grow to 750rwhp (d1sc procharger) just by swapping out pulleys.

id go turbo or procharger.

Thinking about doing the L92 heads/cam/LS3 intake now as that will lower my compression enough to add a power adder later.

Nitrous LOVES compression.

I was under the impression 12:1 was too high (realistically) for NO2.

Im no N2o expert by any means, but from my understanding the more compression, the more hp you get from the same shot of juice (within reason obviously). I would think if you are running higher then normal compression, then it would require a tad more timing retard to make the shot safe. However, depending on how much you are wanting to shoot, the compression may not even be an issue.
