Hello, new member here. I frequently read this site for good info on almost everything, theres alot of knowledge here! I would like to lend my assistance to some of the more street and bracket oriented guys. I will admit what i dont know, ive been out-of it for a few years! I have been working on or rebuilding motors, trannys, and rear ends for almost 40 years both privately and professionally. This includes almost everything from pulling garden tractors to large diesels. My father who was an R&D engineer had over 60 yrs in the field as well. When I had the farm auction we had close to 140 engines up to v12s not counting anything single cylinder. that was for our hobby and not including my professional work. We drag raced mopars for 13 years at 4 different strips with 2000+ passes at Osceola alone and never had a new engine to start with, only swapped one at 150k+ mi because of wiring everything down from extreme blowby. We never broke anything and almost all parts said Chrysler on them and were driven to work daily. All had big cams (up to a .590 with 1.6 rockers) and were over 4500lb None of them had 1 carburetor, none that were raced had over 8:1 compression. And for a few years were the winningest cars at Osceola dragway and won the street sleeper award at the nats. We had a machine shop where at one time we made a set of dome top pistons from billet aluminum for a pulling tractor. I only say these things to establish some credibility. My feeling is that in alot of cases I come across I hear their goals and end up saying "you spent too much and left too many original parts lying on the shop floor!" Ill try to keep this brief (ha ha) but basically if ma Mopar did it there was a good reason! Like adding deck height and long rods to an RB. adding extra material in the right places to six pack rods (ive had stock bolts to 8k rpm on them briefly) using larger rod journals, piston pins, and longer heavier piston skirts than chebby. Those were all bad failure points in BBC heavy truck engines. Talking to professional builders like Gearte, Houge, and Alber about floating pins and other stuff and them saying yes, if it was a chevy, but ya got a mopar with good rod ratios and a short stroke, dont worry about it! Getting 21 mpg in a 4700lb (our first 6bbl newport drag car scaled 4860 with driver) with 4.10 gears, a good size lumpy cam and 2 large thermoquads on a long ram 7.75:1 cc'd compression 440 that lifted the front wheels starting in second and spun the rear tires at 107 mph when the engine flashed to 7k rpm on 87 octane. I have whitnesses who ran hot mustangs with NOS that wouldn't ride in it again! Dad ran a 64 sport fury 4 spd with 413 long rams and 4.56's back in the day and im building an extensively caged and lightened 64 polara 2850 lb(with iron heads and 2 batteries)drag car into an 8-71 blown injected 446 ci street strip car. Theres more but thanks for now!
for joining.
