MavarickGrabber. am I doing damage to my motor? I am using a 73 302's balancer, but my engine block and crankshaft are an 88.
sounds like an imbalance problem,.do you notice vibration running it? shaking at certain rpms?....your engine needs to be the correct balance with both the harmonic balancer and flexplate to correspond with the interenals, otherwise Yes you are doing damage.
RadMav is correct. That is the wrong balancer. The 73 uses a 28 oz balancer whereas the 88 uses a 50 oz balancer. I believe the switchover year was 81, so any balancer for that year or newer will work. You need to change it before you damage the bearings.
Ken... ...I have seen several mistakes in magazines. What gets me is mistakes in some of the books in my 'library'. Many are published by Motorbooks International. Occasionly I read conflicting information in them. I am pretty knowledgeable about what cars came with what options, even Chevrolet makes. Chrysler products are still quite a mystery to me and until recent years I would pass right by them at a car show. I respect your knowledge of old and new performance. My education stops with carbureted models. I was taught from an early age how to repair and rebuild just about everything on a car. Even though my Dad was a mechanic, most of what I learned was on older vehicles as that was his primary interest. He is retired from the military, although now he is a shop foreman maintaining construction equipment. He knows much more about the 239 V8 in his '54 Crestline Victoria than he ever will about his '97 Mark VIII's 4.6 and the complex components under the plastic shroud in that engine bay. I should have learned more about modern mechanics while I had an SHO, but I depended on it for daily transportation and that is not the type that I enjoy repairing and maintaining myself. Thank you for all of the great advice you give those in need on this board. Seth
sounds like an imbalance problem I was under the impression that since the small block Ford is an externally balanced engine the flywheel and damper had to both be either 28 oz. imbalance or 50 oz. imbalance (in other words matched), but the crankshaft itself was neutral and wouldn't affect balance. The only crankshaft change I was aware of is the different diameter at the rear where Ford went to a one piece rear main seal.
maverickgrabber, You are the one that told me to rip the trim off of the car and throw it in the trash. HAHA! By the way that LS1 is going to be out this weekend and he said he is looking for a yellow grabber.
Little Red Toy, I work for Motorbooks International. We contract our books out to people like Evan Smith, who are the "experts" in certain areas. Even the experts disagree on data from time to time. While I receive the occasional complaint, I have no idea if the person filing the complaint is right or the author is right. Many authors just get their data from other books, so if one person makes a mistake, many people after them do as well, and the mistake becomes fact after a while. It's too bad, but it is the nature of the business. I have seen head cc charts that have been all over the map as well. While many of the books are published by Motorbooks International, many are also published by Car Tech (SA Design, Krause and HP Books. They actually do a fair number more engine books than we do. Just an FYI.
I can only hope for that, because that car traps 109-111 mph. Honestly I am tired of hearing him run his mouth, so someone needs to WAX his LS1 REAREND!
ordered the carb and some E/T streets and a torker II intake going to see how it runs with a single plane should make a lot more power from 3000 rpm on
you need to get my number and call me i have the guys number for the motor you can call and see if he still has it
