Re: 68 Yenko clone
Gentlemen the camaros sold in 67 and 69 with the auto tran's, had hydro, lifters, There H,P. ratings were 1967 410 H.P. 1969 425 H.P. There are no hydro. lifters on L72 427 V8's. In 1968 all camaros were m21 4 speeds, with L72 427's The L36 was producted according to G.M. from 1966 to 1969. G. M. futher states that the L36 was ment for large pass. cars,, med. trucks, but also found it's way into corvettes, plus the large body bel air, Impala car's in the late 60's.the same motor with 3x2 barrels in a vette was rated at 400 H.P.With a diff. L number.I had one in 69 an L36. As to 67's,most had the blocks changed at dealer(yenko) except auto trans cars.Factory built that way,the tranny's of the day had a very hard time in auto form handling the H.P. of the L72. All 68's had 4 speed m21's,L72's(as all the three year's should have had, no auto's) And the majority of 68,s had the L72,s FACTORY installed and all 69's.This comes from several people who I talked when I worked for chev. in the mid 70's,who worked on this project for chev. yenko over rated the H.P. in the 68 camaro's from 425 to 450 also the 69's, the same. the auto trans camaros were also over rated. 67 from 390H.P.to 410, 69 from factory rating 390 to 425 yenko H.P.?The 68 4speed camaros, L72 factory 425, yenko 450H.P.But in his defense he did modify them some. never heard of a L-88 yenko camaro, but thats just the ones I saw shipped to minnesota. Question of the day whats a ZLX 427 chev v8. thank you Bob krueger.
