There is a block around here i can get really cheap, question is, how big can you go on one? nothing crazy, but ive heard u can take a 5.3 to a 5.7, so 5.7 to.....? any good combinations you all could recommend? thanks, chris

 

3.905 bore

 

cool deal, stroker kit, cam, and 4.10s, i should finally be able to hit 13's, lol, thanks regency

 

small tr220, 3600 verter, and 4.10's with the right tuning would be 12's!! ls1 should be low 12-high 11's with the right setup. put verter, and built trans on your mod list.

 

i was looking at a trick flow power pack, in summit, claims 500 hp and 460 lbs with a stock ls1 with 10-5-1 compression and ls6 intake. got me wondering

 

11's are pretty hard to get, TRUST ME!!!!!!! On motor anyways...lol!

That TFS package isnt what they claim it is. Especially without atleast 11.5:1 CR. Also alot more than what they tell you, is that you HAVE TO run aftermarket rockers with the TFS heads.

Ohh and my trans is the STOCK one that was in it from GM, I added a 24,000 tranny cooler, Transgo HD-2 shift kit, vette servo, billet OD servo, and tried to kill it with the TCI Competition 3800 stall (but still havnt succeded, and killed the verter once...lol). Ive got almost 70,000 miles on the trans at the moment.

 

thanks again for the input, if i could run mid 12's i would be happy as hell, before i buy parts, get ready to be pm'ed regency, lol

 

no problem man, feel free to pm me as much as you need. I will help you as much as i can.

 

Your transmission will break into 3 pieces and fall out of the truck on your way to work tomorrow......

 

just my $0.02 an iron block ls1+boost+built trans+traction you got easy 11s maybe 10s you can live the rest of our dreams
