Nu-Tek short block back,what you think?Power guesses?
Drove up there tuesday and picked up. Man, did it look good. The specs are...
383 short block
11.8 comp ratio
forged rods and pistons
cast steel crank
speed pro rings
custom cam grind - Int. 228 Ex. 235 LS 112, Valve lift w/1.6rr
int.- .560 ex- .579
Heads ported by Lloyd Elliot (flow numbers below from Nu-tek)
Ferra Valves
Comp 987 springs
Int. Ex.
.100-- 62.80 49.10
.200-- 133.90 98.90
.300-- 194.40 133.50
.350-- 215 148.30
.400-- 232 159.90
.450-- 245.60 170.30
.500-- 256 177.90
.550-- 262.40 184.70
.600-- 266.80 191.10
I'm really pleased with the heads, Nick at nu-tek said that they were the best flowing set of ported stock castings he has flowed so far.
I'm using all the bolt ons Hooker Lts, 58mmTB,Electric WP, MSD ignition, no cats, Dynomax mufflers, (free mods) and having it tuned on the dyno by Carolina Auto masters.
So what do you guys think will be the final power output? Anyone with a similar setup got some numbers to relate?
