    hmmm, not 100% sure of that. If anything i could always go with RHS LQ9 heads or the PRC 265cc LS7 LSX heads. I think ETP makes LS7 heads at 265cc also. Either way the flow numbers are pretty much the same so i wouldn't be sacrificing anything....

    Im going to look into that tho thank you!

    Sorry that head info is incorrect i just noticed it.

    These are the correct ones:

    Total Engine Airflow 245CC CNC Ported Trick Flow LSX Cylinder Heads

    245cc Flow Data



    Intake Exhaust
    0.1 69 56
    0.2 146 130
    0.3 237 201
    0.4 294 249
    0.5 336 269
    0.55 348 273
    0.6 353 276


    Tested on 4.185" bore @28"

    And these are the PRC LS7x 265cc 7.0L CNC Heads i was considering also

    Flow Data: @ 4.125" Bore Plate Superflow 600

    So you only expect to make 585rwhp w/ this combo? I'm pretty sure you could make that w/ the 454 alone let alone w/ the F1. More like 1000rwhp, probably more than that. For that kind of power I would think you'd need waaaay bigger injectors if it's anywhere close to what I think it could make.

    Well, i was thinking the engine alone with the supporting bolt-ons would net somewhere around 600RWHP/TQ. With the F1C at a reasonable 12-15PSI i probably could make 850+ but then i would need a DFi and all that other crap which i was really hoping to aviod but hey, if you wanna make BIG power, better be prepared to pay BIG bucks!

    And i edited the Build Sheet estimated HP/TQ thank you!

    Injectors are probably going to be too small. Even for the 454, add the F1, I cant help but think a 60 is way too small.

    Did you tell the engine builder that this is going to be a FI build? What compression ratio are you aiming for, and what did they say this combo is going to produce?

    Why the LS2 conversion with 58X relucter wheel? This is going on a TA right?

    Double roller is still causing people problems. The LS2 chain is good for most people, probably not for this build. Ask around for different chains. I know a sponsor at the other site had some real C5R chains. There was also anothr chain I cant remember the name of. It was very pricey, but had a great rep and would get you away from the double roller.

    Have you ran this entire combo, plans, and end result goal over with the engine builder? They are the ones that should be telling you what to do in this situation. Most of us have not done such a build, and are probably not qualified to give thier opinions here. Myself included.

    Yes, your right the injectors are too small, i found some 96# injectors but there low impediance and i really want high. Figured the 96# would be sufficient for the build because the whole fuel system (lines included) are rated to 1200hp.

    I talked to the builder and he said for a FI setup he was looking for the CR to be approx 8.5:1 or 9.5:1 to be able to handle a decent amount of boost, nothing crazy.

    I was told from TSP that the LS2 conversion and the x58 reluctor was necessary for the swap, never really gave it much thought or questioned it. He did give me an answer but i dont remember the answer.

    I have the double roller on my car now. Granted it's only making 450RW but i'll look into the C5R one.

    I am working closely with the engine builder (my friend) and figured i would go on this board to get other alternatives to some parts i've listed to replace them for better ones i.e. the double roller for the C5R (thank you BTW) So just gathering opinions then i go running to look for the part at the best price and will SLOWLY lol start assembling pieces of the engine.

    I know thata most ppl on here may not be the best qualified for such a different build but they have a unique knowledge of the LSX cars and hi-performance parts to go with them and that's why i'm asking so i dont make a mistake and everything goes as smooth as possible the first time

    So thanks pal for your opinion i will look into the C5R and if you have the name of the person or website that sells the real ones please message me!

    Alright, for the C5R chain, look up Katech. Pretty sure they are right down the street from me.

    The other chain I was thinking about is the Cloyes Hex-Adjust with the IRL chain sold by Skoggins. Call SOON. They were limited production, and they were selling off the last few sets quite some time ago. If you can get your hands on that, its the best chain, timing set available known to my reading abilites.

    Look into that other chain also. Compare the two prices, and do some research on the two. Awhile ago, some knock off C5R chain were being sold, Katech is a trustworthy source.

    I think the Katech C5R chain price can't be beat, it's only $30 more then the one i was originally supposed to get which is awesome!

    also i wouldn't worry about changing your coils..the ones on our cars should be able to handle anything you throw at it ..within reason. and also..keep a eye on your fuel pump..i would go dual just for safety ...
