**** it, build a 427 and let it eat

If GM can do it, and the Ford guys can do, so can we haha

 

For a daily driver and smal blower and go with iron block for durability and if you want more cubes bore slighty. the tq of a stroker would be helpful with a heavy truck and would say go that route if n/a; but since your running boost more rpms will help spin blower faster if you want without pulleying down and keep rotating assembly happy also wont have some of the inconviences of a stroker with a blower. Then do some cnc work on stock or ls3 heads or if want a good bump in power get some decent afr or tfs heads.

 

I am on this page.

 

I see the 370 is the most popular here since it uses the stock stroke, Paired with what head tho would make it perform the best with the smaller blower..? I guess also the 370 with the 1900 and the smallest pulley probably would only see 10 psi..?? What crank/rods do you guys prefer for a boosted ap..?

With having now a stock bottom end 6.0 and 317 heads are their any heads that will flow better and make more power with the 1900 and my mild cam..?

 

L92/LS3 heads out flow 317s, however you can send your heads to PRC and they will come back workin real nice. The general consensus is that cathedrals are more torquey than squares

 

All depends if you have future aspirations beyond a 1900. I have a build thread for my 370 in projects section but I think my goals are a bit higher.

 

I think i'll stay with the 1900, i'm not building a high hp race motor. I just want it to have a little more. If i could get 50-75 hp more out of what i have now it would be great. I thought about buying a short block, long block or even just heads if it would warrant what i want.

 

A set of worked heads would certainly help it. Do you have a LQ4 or LQ9?

 

I went with a factory bore/stroke since I run mine day in and day out and since boost was limited, I spent the money for the aluminum block. No one would recommend a stroker for daily use that I spoke to.

 

Lq4

I was told today with the few phone calls i made that a set of ported 317s would help some. I thought about those and a phenolic blower spacer on my current setup but not sure what those too will do power wise....any opinioins on that..?


Also within those calls i got quotes on a 370 long block with forged rods, wiseco or diamond pistons and a gm nodular crank. Plus the timing set, arp studs, mls gaskets, arp rod bolts etc, Pretty nice about the same from texas speed 7800, thompson motorsports 6500. Not sure what to do with that. I thought about buying the heads now and then the shortblock later.
