i wanna try an allmotor ls .. want ot know what are some good pistons for it and still be able to drive it everyday

also .... was wonder how much power do you make with b20 cams in an ls head

A lot of NA LS guys are using P30's. If I were to build an NA LS those are what I'd use.

B20 cams are essentially the same as an LS so you probably wont see any gains

yea i would go with p30 B16 pistons as well...they yield around a 11.3:1 compression...

i was going to go with ctr pistons and flat top valves and get my head milld

Do you plan on running race gas?

jdmG2kid · **Posted:** Wed Feb 13, 2008 6:29 pm

maybe mixd gas if its not over 12.5 then im good i really dont have to run it but then i would have to run 550cc injectors ..im just trying to make sonme power i no its hard to get 200hp out of these things

im tellin you right now that with CTR pistons and a milled head = BOOM! if anythin just mill the head with B16 pistons and you'll be set... the power you make outta ur motor is around 20% outta the block and 80% outta the head...if you want a lot of power then be prepared to spend some money on headwork

jdmG2kid · **Posted:** Wed Feb 13, 2008 9:40 pm

yea boom ..... will do some head work .... i see that p30 pistons make more power than p73.. what is the most power i will get wiht 403 skunk2 intake mani and tb and a tdm header

Integraguy04 · **Posted:** Thu Feb 14, 2008 8:59 pm

well i could def. see 180whp

jdmG2kid · **Posted:** Sat Feb 16, 2008 9:20 pm

soo would p30 pistons be good and get the head milld

Does it need to be drawn in crayon for you :?:

J/P man.

Integraguy04 · **Posted:** Sun Feb 17, 2008 9:50 am

yea man...honestly you prolly dont even have to get the head milled...i mean if you want that extra compression you can but i mean there are other ways like a 2 layer headgasket/flattop valves etc...to bump up ur compression...i really never liked milling a head/block IMO but thats just me

jdmG2kid · **Posted:** Wed Feb 20, 2008 3:41 pm

yea i am going to get flat top valves and milld im just trying to get power

Integraguy04 · **Posted:** Wed Feb 20, 2008 6:17 pm

yea check out the thread on the 200hp all motor ls...
