I graduated from high school in 77 , and remember buying a 68 charger with a 383 4 speed for 200.00 bucks in Addison ILL. , smashed it couple years later , then bought a 69 roadrunner 383 automatic for 600.00 bucks, back then all those cars were plentiful, miss all those days, a lot of good memories.
I wish I could miss those days! Back then those cars were a dime a dozen, just like the Iroc Z24's, Stangs, Montes and such cars were back when I was young and dumb smashing cars cause they were cheap! I guess every generation does it lol
I guess could have worded it differently. The Stage 2 cam was designed as an upgrade for the 400-430 heads before the Stage 2 455 heads were available. When the 455 Stage 2 heads were released the Stage 2 cam was not redesigned for the improved exhaust port and was simply a carry over . I understand the lead time on engineering and development at the manufacturing level . But I'm sure there was a Stage 1 developed before the Stage 2 . And Yes the standard valve was before that also . I don't know the time frame but based on option availability I'm pretty sure it was sequential.
I had thought the Stage 2 cam was the same for the 455 and Stage 2 heads. Just how much power would you lose putting a exhaust on a Stage 2 cammed or Stage 2 headed car? as Denny Manner info mentioned in all the articles. The factory GSX Stage 2 that ran the streets had to have a exhaust i'm guessing? Did they un cork it from the headers when street racing?
Too many variables to put a number on it . Cam design would be a factor . ..3.5 inch exhaust with Hi Flow mufflers and turn downs at the diff or the Factory 2 inch with mufflers and tail pipes or only cherry bombs that bolt to the header flange All would have different effects on power .
I remember when I was in high school 80-83 I saw plenty of Hemi Cars for 4-5K now the same car is worth ten times as much. My first car a 69 Chrysler Imperial LeBaron literately had every single option on it. The original owner was the dealerships owners wife, He checked all the boxes on the order sheet. I paid $300 for it. Even though my GS had the 77 V6 transplanted into it. it still looked like a 70 GS stage 1 car. I would get the looks. My winter car (winter 82-83) was my grandfathers 74 Le sabre. I remember a friend had a 71 Torino for his winter beater. Tim
Tim, what?? Your Stage 1 had a odd fire v6 swap in it?? Did the Chryler have the "posi" or "sure grip" checked off on the order sheet?
So my new book showed up today, after seeing the post about the lost muscle cars book I ordered one. Just before the Tony Branson article it talks about the factory built GSX stage 2 car. Which a couple of guys on here have look a like cars, the original was destroyed but the hood ended up on the Reynolds car.
Just to clarify the hood of the white GSX stage two prototype did not make it on Reynolds KB car it's on the red J+B stage 2 car.
Reynolds car had the complete hood with air pan, come directly from Buick’s engineering department through Dennis Manner. Already painted....
Attached should be a picture of the Holley base factory intake manifold. It appears to be a 67 intake due to the lack of bolt boss provisions for a throttle cable bracket.
Thanks. Cool intake, and a choke stove spot is it? love the old engineering. These guys were the best Pencil and protractor engineering Math w a pencil paper and brains Lost technology they used 850 Holley carbs?
No idea nor indication what carb was used on it. Most likely there were several different size carbs tested.
