What year and why did the 396/375 replace the 427/425 as the engine of choice in the A/SA '69 Camaro?

Frank I still think the 427/425 is a good combo. I ran a 69 Camaro with a 350/255 for several years. Jimmy Marshal would always tell me to put a big block in it and have more fun. He was right in some ways but he forgot to tell me that it would eat a lot more money. I chose the 396/375 Hp because at that time the Aluminum head for the 427 was ten more Hp than the stock steel ones. My back was already not in good shape so lighter was better. Seems most of the guys that run the Aluminum head 427 like to run in AA. BP

I like to read posts on this topic. I usually don,t post. When Allen mentioned the index adjustment a few years ago i thought it was time. I just purchased my 390 67 Fairlane post car in 2008. It ran about 4 tenths under the index here in division 4. The next year i freshened the engine and up graded the camshaft, ring and piston package and picked up about 5 tenths. My engine still had the OEM crank and iron heads. If it wasnt for my friend and racing mentor RJ Sledge i would have never got there. So they lower the index 3 tenths so i gained 2 tenths for all my effort. Now with that being said i think a index adjustment may hamper new people to get started in this type of racing if they dont have the funds to buy a top notch car or try to build there own on a budget. I was told from day 1 that this is a expensive sport and that proved to be so. Each year i would try to improve the car and slowly was able to improve performance. Anyway no matter what happens iam still game. Currently building a SSGT.

Kirk I don't have the information but I would like to see them post all of the new Stock racer that have joined the Class in the last 5 years...I'd be willing to bet most have not built a car from the ground up. And the few that have knew what they were doing and went to a Stock engine builder. The problem with the AHFS the way it is now will put almost all the engine combo's in the pool to get HP at the end of the year. And for those who's car's can't run that fast there are others that may run your combo that can. Take a look at Indy qualifying this year in crap Indy air. The easy fix would have been lowering the index's a tenth. A lot of racers didn't want that. But as they say be careful what you wish for. BP

The aluminum head is still a 10HP penalty on the 427/425. We ran it for years. We never had a high dollar set of killer aluminum heads, so I guess that's why I don't care for the combination, although I could put ours together fairly quick, and without breaking the bank. I just don't think it would be fast enough to suit me or be really competitive. I bought my old iron heads back, and I have another pair. They're all going to be checked and flowed. I don't know what we're going to run yet, if we run. I'm thinking our aluminum heads will be better on a 396, which I have a few parts for. If I were running a 69 Camaro myself, I'd be looking at the iron heads on the 427, and a four speed.



Myself, I want to go with a 69 Chevelle. My two favorite Stock eliminator cars ever, are Harry Vineyard's 69 Chevelle, and Kevin Borgstrom's 69 Chevelle Yenko clone. Who knows, maybe I can sell off enough stuff and get lucky.
