With the sb chevy being so popular and lots of people doing write up builds on them from mild to wild. How come you never see or can find any write up build on a blown sbc. I have been looking in lots of hot rod mags. I have a 30 over 350 which keeps blowing head gaskets no matter what kind or thickness. I am running jahns 8:1 . I have taken it out now and like to build it. But I would love to read a write up on one someone has build. Con sering pistons,cam,heads and etc. I am thinking even the clearances and specks should be different then a non-blown eng. There lots of great machine shops around, but when it comes to blown motors they are a different animal. I am not looking to build a monster. The car does not need it. Its like a weekend strip/street warrior. Its a 1,358 lb 97 inch wheelbase car. 350 and the blowers a 8-71. And yes it has a frame that will hold most anything 2X3 tube frame 4 link with a 9 inch. With a 6 point cage. Has anyone seen any write ups. I have pictures,just not sure how to post them in this forum. Can email

My first guess would be either your block surface is off and/or your heads are warped. Is the block O ringed? I'd definately have them checked first. Are you using head bolts or studs?

X2, i would say you surfaces are not level

Thanks Larry and the PM on your Nova. I will try what you said. Also I will try to attach a few pictures of my car. I have more if the make it. Its mostly a street car , with state tags. But still like to see it make down the 1/8 mile with good times. See if you can catch the year/model. Very few of these around . O' The block was decked and ccd, the heads were surfaced and ccd. And head studs were used not bolts. Its not o ringed, but I guess thats the next step. Later guys !
