Postby busterrm » Sun Oct 21, 2012 5:35 pm
Here is the build sheet so far, still haven't made up our mind on the roller cam.
1. New Chevy Bowtie Block 4bolt roller block
a. bore 4.03
b. stroke 3.75
c. 1 pc RMS
2. AFR 195 elim Alum heads
a. 65 cc chambers
b. 2.05 int valve
c. 1.6. exh valve
d. spring/valves for 600 lift
e. closed pressure 135 lbs
f. open pressure 325 lbs at 600 lift
3. Rotating assembly
a. Scat cast steel crank
b. Mahle forged pistons
c. Lunati 6" I beam stroker rods w/7/16 capscrews
d. All bearings are Clevite
e. Rings are Hasting chromemoly
4. Roller cam
a. Crower 0471 hyd roller
b. Lunati 60131 solid roller
c. Crane HR-234/365-2S-12.90 IG hyd roller
5. Roller lifters
a. OE roller lifters by crane
b. spider plate and alignment donuts
c. pushrods ?
6. Intake and Carb
a. Edelbrock RPM performer
b. Holley HP 750 vac sec.
Thats what we have so far! My only questions are when it comes to the pushrods with the OEM style roller lifters will the pushrods be close to OEM specs or longer, what do you think? What do you think will be a more streetable cam? The truck is stock weight 1990 Chevy 1/2 ton silverado, 700r4 shiftkit, Coan 2800 stall converter, 373 rear gear. Whichever cam is chosen will have to have the step nose machined on the gear end for the retainer plate to bolt up. Any help or opinions would be great guys.
