Drewster67 Posted January 8, 2015 Share Posted January 8, 2015 So - I did the bottom end last summer - now I'm on the quest to do the top end. This is my current short block setup Forged Probe pistons 3.902" Flat top -3cc TMS performance rings Blueprinted GM block L33 core GM connecting rods TMS remanufactured cores GM Nodular core crankshaft 010/010 high speed balanced King racing rod bearings King racing main bearings Thompson Motorsports single piece racing cam bearings This short block is rated to 700HP I'm looking for suggestions on how to build the top end. Cam Porting New intake New Larger Throttle Body New Larger fuel rails Reputable - reliable machine shop to do the head work. Tune Im looking to achieve at least 400-450 rwhp. Lets start with cams - Need something aggressive but not too aggressive to the point where I can't drive it on the street. If I change the cam - what else needs to be done? Valves - Springs.. etc .. Thanks In Advance!! Drew Link to comment Share on other sites More sharing options...

Cam: Custom grind from us ;) we use ed curtis btw Porting Advanced induction ported stock heads, or for less downtime do a set of AFR heads New intake Fast 92 or 102 setup New Larger Throttle Body If fast 92 do an oem ls2 tb, if 102 do a nick williams 102 or tpis 102 tb. New Larger fuel rails not needed, would be solely for cosmetics Reputable - reliable machine shop to do the head work. see first statement about advanced induction Tune nic d obviously Im looking to achieve at least 400-450 rwhp. a nice driving cam on an ls6 w/ stock heads/intake manifold will easily hit 415-420 rwhp. Throw on a good set of heads and a fast manifold you will be at your 450 goal. Lets start with cams - Need something aggressive but not too aggressive to the point where I can't drive it on the street. If I change the cam - what else needs to be done? Valves - Springs.. etc .. when doing a cam you will get new springs and pushrods. we also upgrade the rocker arm trunions too. Thanks In Advance!!

Unreal Posted January 8, 2015 Share Posted January 8, 2015 Agreed with Joe Ed C, Pat G, Brian Tooley AI for heads if you don't do aftermarket Only thing I would say is wait for new intakes. The new MSD, Vararam, etc intakes are out any day and may be a lot better, or may drive the fast prices way down. Fuel rails are just for looks. Other thing is what style heads you are going for. I would assume you are staying cathedral port instead of swapping to square port based off the bore size. Link to comment Share on other sites More sharing options...
Guest badbobs95 Posted January 8, 2015 Share Posted January 8, 2015 I would do all of that and then, well, I don't really know! Link to comment Share on other sites More sharing options...
Dvl4evr Posted January 9, 2015 Share Posted January 9, 2015 Any particular reason for doing H/C package instead of blown? Going to be similar $ won't it? Link to comment Share on other sites More sharing options...

Yeah - I meant to say fuel injectors in my original post ... lol Im not sure but I think it will be more cost efficient to have my 243 heads ported . but I really have no idea - I'm getting myself familiar with the different configurations/options available.

Drew Thanks for the heads up Joe! - Can you please write me up an estimate for the work you described in your reply - and email it to me? Keeping my heads not going to do aftermarket. Whats the difference in Fast intakes? I'm guessing air volume and pricing?? I need an estimate with 92 FI with LS2 TB and one with 102 FI and ?? TB - Ill follow up with you once I have an idea what the pricing looks like. Thanks Man! Link to comment Share on other sites More sharing options...

Whats the difference in Fast intakes? I'm guessing air volume and pricing?? The 92 you can run an oem GM throttle body (90 mm) The 102 manifold you can run either a 90mm TB or do a NW 102 TB obviously a 102 TB is ideal given the manifold size. Sometimes you have driveability issues w/ a big throttle body like that as they let in so much air with minimal movement. If you major concern is perfect driveability and not the absolute max hp you can get, do a 92/90 setup and if you want we can port the fast 92. I need an estimate with 92 FI with LS2 TB and one with 102 FI and ?? TB - Ill follow up with you once I have an idea what the pricing looks like. Thanks Man! Will have it emailed to you in a few min.

Unreal Posted January 12, 2015 Share Posted January 12, 2015 I really would just do a ported ls6 intake or something like that until the next round of manifolds comes out. MSD and Vararam in the next 1-3 months will have new intakes. Either they will be great and you want one of those, or they will drive fast prices down, but buying a fast right now right before the market could completely change seems like a bad move IMO.
