[LIMEY VALIANT]

I would really appreciate some help from those on here who have REAL WORLD experience of building and running blown race smallblocks

When I had this blower it was on a fairly standard 360 and I ran a 11.336 sec.

I have since run a 9.844 on my 408 normally aspirated

I am now looking to build a new 318 based blower motor and this is what I have pencilled in thus far :


ALREADY GOT :

6/71 blower with several sized pulleys
Twin 600 4 barrel carbs
Snow performance kit for twin carb rootes style blower
Indy heads mod man single plane blower intake
Aerohead 70 cc heads port matched to above intake. 1.88" x 1.6" 3 angle valve job
Donor 318



WAS PLANNING TO BUY :

4340 forged crank 4"
6.123" forged I beam rods
Forged dish top pistons giving approx 8.5 - 8.9 c/r @ 70 cc head
Cometic 0.040 head gasket
Machine and bore block to 0.040 to give 397 c.i. ?
Plasma moly file to fit rings
Custom grind 114 deg sep cam


In particular could do with some help with cam / lifter / rocker spec

Thanks in advance

Here`s the blower on a standard 360 I had
