I got a call from a guy I have not heard from since the late 1970s (LARRY) when I helped built him a 468 big block chevy, for his 1966 chevelle
he had since moved to TENN. and then stored the car for several decades but he pulled it out recently and says hes having a blast driving it.
I get calls from the guys Ive either built or helped build engines in the past, fairly regularly when they want to upgrade or verify what we used.
or in many cases want those engines refreshed as most of those engines are still running (mostly because I tend to favor durability over peak power in a street driven muscle car engine build) but Im surprised at how many guys only drive their weekend project cars just enough that they get driven, and have those same cars decades,later in fact I rarely hear anyone with a negative comment, and I occasionally hear from guys that are second or third owners of those cars.
I got this picture off the internet but its very similar in appearance, to this car
we got to discussing what by todays standards was a real old school build I don,t know what horse power we made but it certainly got the car running street tires into the low 12 second bracket on street tires, which back then made the car much faster than average
but hes had the car running, off and on occasionally for 36 years with the engine that we rebuilt and wants it to go back together again as similar to its original late 70s config as he can get it.
yes hes required to use race octane gas since SUNOCO 260 is no longer available at the corner gas station like it was when we built the cars engine
the cars got a 12 bolt rear with 4.11:1 rear gears and a MUNCIE 4 speed transmission
we used a fairly radical chevy flat tappet solid lifter cam #3959180
crane roller rockers, he has are more than likely some of the oldest still being used
we used a corvette aluminum intake with a holley 3barrel carb
PORTED, RECTANGLE PORT OPEN CHAMBER HEADS
we used manley 7/16" push rods

a 4 bolt main cap block, LS7 connecting rods and crank and
TRW 12.5:1 forged over bore pistons (that looked very similar to these)
hooker headers, and a moroso 7 quart oil pan were used
that if I remember correctly required a .100 clearance cut on both the valve pockets to get correct clearance
JUST FOR GIGGLES I RAN THAT COMBO THRU DD2000 and heres the results
{now I don,t know how close that is I suspect its a bit optimistic but I sure remember the car pulled well once it hit about 4500rpm
