can someone run this combo through dd for me?
327 shortblock .60 over
flattop pistons 4 valve relief
comp cams 280h 280/280 230/230 .480/480 110 lsa
L98 cylinder heads stock
edelbrock rpm intake
650 holley dp
full length headers into a 3 in exhaust single muffler system
if you can run the 327 combo and then do a L98 350 stock except for
the rpm intake 650 carb and full length headers it would help me out greatly thanks,steve
You will want to 'watch' your compression ratio - Those heads only have a 58cc chamber and you are 0.060 overbore. Its getting up there if you still want to stay with pump gas.
Your head gasket selection will be the deciding factor.

No, those Chambers are 64cc. Unless they are from the vettes which did have 58cc chambers.
ok what if i went with a 350 L98 motor iron heads stock bore
a zz4 cam,vortec heads,dual plane intake,650 dp and full length headers.
just trying to make a decision.thanks,steve
Nah, stock 305 heads are 58cc and they typically run 9.3:1 compression. Cutting 0.010 isnt going to make a difference in compression. Maybe .1-.2 at most. I would figure 9.5:1.
