review my setup! Also posted in drag racing section, Car is full weight street/strip
I'm always thinking about different setups to try to get all that I can from my motor, but over the course of the last year and a half or so I keep coming back to this setup in one form or the other. I think I'm really going to start to pursue this and Id like to see what input y'all here can give me regarding driveability/ characteristics and overall opinions of this setup. So here goes...
Stock bottom end LS1 (flycut) with Katech rod bolts
Vic Jr. manifold, port matched to heads
4150 4bbl TB into 100mm lid via carb hat and SD tune (Id drop the carb hat/lid for all out runs)
Current PRC 2.5 5.3 heads milled 59cc with a bit of touch-up
GM MLS HG's
Crane lifters
236/240 .607/.609 110 +2 (3017R/3730R/110 LSA/108 ICL)
Some form of UD pulley
All of this feeding into an M6/9 inch, and a mandrel bend 3 inch dumped H pipe.
Things I have yet to decide upon...
Use current 1 3/4 headers, 1 7/8 headers or stepped design
Use 4.10 or 4.30 gears
Again general impressions or input would be appreciated. Thanks all!

Sounds like a drag setup but want to use it on the street. With the 4 degrees of advance on the cam, it should help out with the street manners and low end power. I would get the 4.10 gears, the other is a little to steep IMO. Stick with your current 1 3/4 headers. I'm sure I'll be crucified for saying it but the 1 7/8 is not gonna benefit you virtually at all with a 346 c.i. More cubes they would. If you are intending to keep using it for street use, I would not dump the H-pipe. Stick at least some bullet mufflers on it or unless you love not hearing yourself talk.

I have the floor under the seats sectioned, I can fit a full sized muffler on each pipe with better clearance than a y pipe. Currently have dynomax proflow's but one of them died this weekend so I'm considering flowmaster 40's, just concerned about drone.
Yep pretty much a street strip setup. Thanks!

Sounds good to me im thinking the 4.10s and the 1 3/4 headers will be fine sticking with the stock bottom as far as exhaust its all in what you like some dont like drone some done mind... but hurry up and get the thing out on the streets so I can see it!
