Well my shortblock is almost done and i've got everything i need to wrap up my build except a cam. I've done tons of searching and still haven't been able to decide what to use. I'll be using a 3200 stall, 317 heads, weiand intake, and spray a 200 shot at most on it for the track. I don't want to sacrifice horsepower on the street just for a few more when its on the nitrous though. Any suggestions? TIA

 

i sure hope the 317s are well worked over, and that 3200 is to small IMHO. for my 408 im running a 244/248 612/615 112+2

 

heads will be stock for now, money is starting to dry up and unfortunately at this point they are the best i can afford. I like the 3200 for the street since this is a DD, i may change it when i see how it drives with the new motor though. Oh and i forgot to mention im not looking to make anything crazy on this motor. 425rwhp on motor would make me very happy for now.

 

id look at a different intake manifold if you dont have that one yet

when v8 did the swap he gained nothing if not lost soem wiht the weiand - its ALUMINUM as in a heat soak get a polymer intake (LS6) or a edelbrock vic jr( i know aluminum too, but seen really good gains with it - woodhauler, parish)

 

might look at the TSP torquer v.2 or v.3

 

The reason for the aluminum intake is so i don't blow it apart if i get a nitrous backfire, since i'll be running a wet shot. I've already got the intake, but i guess i could end up going with a vic jr. still.

 

well your going ot choke the **** out of that motor with 317s, low CR will hurt you also, small diameter headers will hurt ya, restrictive intakes will hurt ya. 3200 is too small for a 408

its a large motor that needs to breath..but if you were only looking for low 400s you could of went 6.0 with a decent cam andcalled it aday

 

ok gotcha,

 

the 317s are temporary like i said, i eventually will probably go with some patriot LS6 heads and that will bump my CR to about 11.5:1. I'll be using pacesetter LTs, no cats, and a straight through magnaflow muffler for the exhaust side. And from what i've seen VIG's tend to flash quite a bit higher than advertised when behind a 408.

 

i knwo about vig i had one
what dish are hte pistons
i know you said temp but just stating, for pacesetters i would look into a 1 7/8 header, a 1 3/4 are small for large cubes

im just going off what i knwo of with my 408 build

look in media section for idle clip of mine....im sure it will make you wet lol
