Back over here now, I dont want to hijack someone elses subject, {re Fitzy} i suppose l am just trying to be thorough, l am going to build this myself
{with help of course] and also going to stroke it, l am just keen to read about other peoples experiences, good or bad to make sure l have
l have as much info as possible and have the best outcome, considering the dollars involved, thats all...,
So early block is stronger than a 5.0 roller block both are fine if you are keeping to low 400-hp and revs around/just over 6k
I always line bore them and fit ARP main bearing studs
They need a good balance job and a good tune, particularly if you are going to rev them, I believe bad tune IE pinging/pre-ignition is one of the causes to block failure if they are on the edge rpm/power wise.
-Mid 10.5 compression is good, set up deck heights etc to achieve this AFR heads have a good chamber and will take compression ok.
-Hydraulic roller cam is good, 270 to 280 deg overal with close to 600 thou lift, I posted some Voodoo cams above, if using a non roller block buy Howard link bar lifers they are good value, distributor needs gear to match cam material
-Air gap intake is good
-750 double pumper carb
-Roll-master red timing set is good
-Cast eagle/scat rotating assembly +I beamrods is fine for this type of power
-Moly rings like Total Seal brand
-Clevite 77 bearing, (eagle crank uses Chev big ends)
- minimum f of 1-5/8" primary, long tube 4 in to 1 3" collector
-AFR 185s are good and have roller cam springs
-Comp cam gold or Scorpion rockers are fine
PM if you want my ph number if you want to discuss what to do.
