Alright, i got a 5.3 and im gathering up parts to do my engine swap, i have most of the parts already but heres what its gana be...

Ls1 short block
milled .30 243s
232-236 595-601lift 112lsa +2
pro flow intake
3600 edge (maybe restalled to 4k)
4.56s
lt headers, ory, 3.5 dynatech
and all the boltons

This is gana be my first ls engine build so any helpful advice would be nice.
any guesses on what it might put down or run??

 

good luck with the build should be a good upgrade but why didnt you consider a 6.0

 

i was looking for eaither but a local guy gave me a fair deal on the short block
so i thought id give it a try, and my bro has a truck like mine that we put a
6.0 in so i figered id see i could keep up with this!!

 

O btw, its going into a 99 scsb.

 

well the 5.7 is lighter and pretty close to a 6.0 with the right setup you should fly by him lol.

 

I'm gonna guess in the 425-440 range on the motor...... I too am working on an ls-6 build in here too.... Will be done one day

 

Its gana be dyno Hennesey ok. on a mustang dyno when its done. Dwain is gana do a speed density tune on it, i was thinking it would put down 380-400 to the wheels. hopping to c mid to lower 12s.

 

ls1 is not an LS6

 

should be a stout setup

 

is there a differnce between an ls1 with ls6 heads then an ls6?? i was told the short blocks were the same.
