I ordered all the parts today for my 388 big bore rebuild. It will be:

- Darton Wet Sleeve LS1 block
- Diamond 4.130" pistons (~10.75 compression)
- Eagle 6.300" SBC rods
- stock crank
- stg 3 heads (2.08/1.60 valves....flowed ~295CFM on an LS1 intake)
- TR224/224 .562/.562 112LSA cam (reuse what I have for a while)

It is/will be supported with a BBK 80mm TB, a matched LS6 intake (~78mm TB hole), Hooker LTs, and a 2.5" x-pipe (bullet mufflers) out the rear


I know the TR224 is SMALL compared to what others are running but I want to shoot for a super sleeper for a while. The heads, cam, intake, and exhaust were all on the car when I made my 400rwhp/385rwtq last summer (100+ degrees out) so I figure I'm at around 410-415 now. Any idea what kind of HP I will see from this new setup?

I'm so freaking excited I can hardly sit still.

 

i'll guess about 440hp/430tq... with the 112 lsa, it won't be too stealthy... i bet a 228 on a 116 would be stealthy tho...

 

Hopefully not enough to allow you to finally put me your rear view.

 

295 with a LS1 intake attached?? Thats like a 330-340 cfm head, I would say 470-480 RWHP, simply because we have seen cars H/C cars with tiny cams (216-218) make real good power. The better the head the less cam you can use to make the power.

 

If I can bring it up to 450-460 rw.....it will be close.......

 

IF your gonna bore it why not get an eagle crank and give it a nice stroke as well?

Either way your car is gonna haul ***. Grats on the setup.
