Well fellows (and gals) the old lube oil gremlin finally got me! I have a full flow block, supercharged 289 that has just wiped out the first lobe on the left bank. The exh valve on the no. 1 cylinder. Unbeknownst to me when I bought this car the engine had been converted to the hydraulic lifters. It has cut down rocker shaft towers, Chevy vales and springs etc. SO I'm stuck with the hydraulics unless I elect to completely convert back to solid lifters. Eg. cylinder heads, valves, springs, rockers, pushrods, cam and lifters A NEW ENGINE ALMOST. Interesting also is that I've always run ZDDP AND STP with every oil change. That's what makes this a strange event is that I took every precaution and the gremlin got me anyway.
Discussion: Has anyone else had a similar experience?
I am not fond of the hydraulic conversion as it gives low vacuum and low compression. I had a customer with hard starting complaints and I found he had very low compression and 8 in hg vacuum when idling. Converted back to R2 cam and solid lifters and the engine came back to life.
