It's going into a very common engine 90° pushrod V8 that typically has a standard crossplane crankshaft, the small block ford windsor. The engine the GM LS is based off of. He had the crankshaft custom made.
This particular engine is claimed to be a (very) old Nascar block and head purchased directly from (insert FORD nascar team here); he claims the lifters are in factory ford locations but we know Nascar teams moves things around when they run their fancy canted valve heads and larger lifters. Customer doesn't even know the lifter bank angles...."what is that? Ummm.....stock". OK that's unlikey sir and you should really find out, but if you're sure, sign here.
I was streetviewing the house I grew up in and noticed Google melted my friend's house.
Ouch. I thought it was going to splash into a nice soft puddle.
Typically measured from a vertical line, as intake and exhaust lifters are often at different angles.
Illustration brought you by Hemi and their flipped intake rockers:
I have honestly never seen anything like that in the first person.
Pushrods running from a single camshaft to rockers which are offset by approximately the same amount you'd expect in a DOHC engine.
Tell me more about this manner of witchcraft.
It's how chrysler has done their "Hemi"'s since like the 50s or 60s. The Hemi's you can buy today in the chargers/etc have two sparkplugs per cylinder too, cause more is better? Not because the FAA requires it in FCA automobiles.
The rockers are typically on a common shaft.
We get silly and mill alllllll that aluminum out of there, rocker shaft mounts, spark plug tubes, all of it, and rotate the rockers so you can put bigger springs and longer pivot length rocker arms on there. Cause racers are silly.
I also did a kit that works with an unmodified head, cause some racers are sane.
Current NHRA Nitro (Top Fuel/Funny Car) rocker kit, also a Hemi.
There's no benefit to Hemi style heads in terms of flow/power over canted valve heads like below (current GM R07 Nascar engine, but the fords and toyotas similar).
