Stealth Camaro

Was thinking about LS7 427 or LS3 416 with TFS headed but I heard bad things about LS7 block with stock sleeves when you add nitrous or boost

This car is an M6 car with 12 bolt 3.55 that will never see the track but only street car that I use it one night every weekend

Planning to do 200-250 shot progressively with C16 race fuel but as you know it will not be sprayed every time like a track car !! Most of the time will be raced N/A unless there is an 800 rwhp supra in the highway

- For the LS3 416ci ( 4.060" bore/4.000" stroke )will use EPS custom cam & TEA/TFS 235 and ported 102
- For the 434ci ( 4.155" bore/ 4.000" stroke ) will use EPS custom cam & TEA/TFS 245 and ported 102

Sure I would like to get Erik @ HKE to build the engine but cannot get him via phone or email ... Maybe I will PM him here

Would be much appreciated if I can find your experience with the strong of sleeved block along,Durability against LS3 416ci ?? any problems with gasket when running 4.155 bore ??

Thanks

For Erik just send him an email with a number he can reach you at in the evenings. Seemed to work for me, but he is very busy and works long hours. Crazy ****.

If you go with the sleeved route and 4.125 bore, you might consider an LS7 based head. Better flowing head would mean less duration on cam and better street manners.

I would think just the other way around. The cathedrals = better low end and throttle response for the street..... cfm isn't the end all

The only people still pushing the tired "cathedral port means better lowend and crisper throttle response" either do not know any better or are selling cathedral port heads.

Pretty good article. My only thoughts were the MAST L3 head, using the same cam as the others, was probably somewhat handicapped over its ultimate capabilities.

I agree but I think that's the case with all the heads. Use a different cam with that TFS head and watch the power #'s. I have the TFS heads on my 402ci so I may be a little bias towards those heads but I know they make power because when my car was H/C/I full weight on the stock bottom end motor I was able to go 10.90@123mph. The car made 447rwhp and 403rwtq.

And it STILL put down good numbers

agreed, the cam handicapped the LS3 heads and it still made good numbers

I was impressed with the CNC ls1 head and the TEA ported 243's...numbers are right there with the rest of them. hp/torque is what gets you down the track right?

Each head has its place. I have ls3's on my hyd. 408 and Tfs heads on my solid roller 408 like em both.

I would opt for the 4.125" bore 427 to unshroud the valves regardless of which heads. A lot of them are running nitrous on that combo, but you're right on the LS7 blocks.
