Which was pretty typical of the aftermarket back in the day because the casting in the main webs weren't conducive to a straight down outer bolts on the main cap. GM redesigned the main webs when they started offering 4-bolt mains.

Good luck... GUSTO

ZBA or ZAB? Either could be correct for 79. ZAB is an L-48.

Still running the # matching original 2 bolt block with studs, steel crank, Summit stage II GM rods with arp bolts. Silvolite 'CAST pistons. Trick Flow G1 twisted wedge heads. About 8.5-1 comp. 6-8 lbs of squeeze for short bursts. Way more than the tires can deal with...and it's a freakin blast!
Talk about your low budget blower build. And all the parts are still where I put em 5 years ago Havin' as much fun as the guys who spent 25 times as I....not to mention any names

Back in the 60's a neighbor and some friends ran a small block sling shot dragster similar to this one...

As youngsters, we thought it was the most spectacular machine around.

He told us it was a "punched-out" 283 (301 cu in I believe). It ran Hilborn fuel injection with a Crane solid roller and a 2-speed LaSalle unit that they shifted into high gear at somewhere around 10,000 rpm! They would usually get a season out of an engine and they were 2-bolt main blocks... at least they started out that way!

They were pretty awesome to watch when they ran, but by the late 60's they were pretty well obsolete. My neighbor ended up parting his car out as there was no market by then for these machines. Some of you may remember them better than I. I just remember hearing them scream like nothing else when they would leave the line.

Good luck... GUSTO
