Did the car top out at 70mph maybe? Lol
It was a bit faster than 70, about 95 +/- after a few mods like a big 2-bbl Ford carb from a truck engine mounted on a “custom” sheet metal adapter. The key to winning on short tracks(ie, the street!) was/is the first 60-100ft.
When I finally broke it beyond my finances to keep it up I had serious money into it. Crank, rods, pistons, camshaft, head/valve work, etc. I launched and shifted at (4 spd Muncie) 8,000 rpm. It would yank the wheels off the ground and run 8.1 in 1/8 mile. Not real quick by todays standards but back then it was a badass street car and unique among the V8 goons.
I won a LOT of street races, but broke everything in the driveline, 12” clutch exploded (had a Lakewood housing so no injury), trans sheared gears, differential spider gears (welded solid 10-bolt) about 6 times including one crankshaft cracked across #6 rod journal while figuring out the harmonics/twist ratio of the really long, 7-main bearing crankshaft.
Only one internal engine failure, but it was absolutely devastating. A total loss of the entire engine caused by a single dropped exhaust valve at 8000 rpm, #4 cylinder..Rod collapsed and broke mid-length. The remainder spun around and cut the camshaft which shattered into several pieces that took out everything inside the block and blasted a giant hole through the block, dumping all the oil out in less than a second. The Offenhauser 4bbl intake and ****** headers survived, but it was over for me and the 67! I didn’t crash, but the event pushed my motivation into the toilet such that I sold the car and everything I had for it.
I spent a LOT of money (I burned all the receipts when it passed $10k and kept going) and broke a LOT of parts, but it was like a college education for me. People skills, mechanical knowledge/ability, studying/research for parts that would fit and perform, history/tracking of every piece/part of the car. Most of what I learned then (still in high school!) also applies today, so it wasn’t wasted money, nor was it wasted time.
Shortly (~4 days) after the big blowup event I was moping around on the CB radio and first met a beautiful young(!) girl who is my wife of 44 years now.
Oh well, sorry such a long post, but that took me down memory lane!
