Subject: Re: Ended the season on a high note by rklessdriver on 2015/11/3 20:22:38 Thanks guys. Stay tuned this winter. I have some more upgrades to the chassis planned and a rebuild/re-fresh of the engine to do. Engine Definite replacement: Roller lifters Valve Springs/locks/retainers Valve Job Rings Bearings Cam Timing Belt Block Hone Rebuild Vacuum Pump May need: Block Bored & Honed New oversized Pistons & Rings I know I just new pistons & rings in her and they only have 2 races on them but that was a patch up repair job to finish out the season and I want to make sure everything internally in the engine is perfect for next year. Also looking at converting my Intake Manifold to a 4500 Dominator flange and buying a new 4500 Dominator Carburetor. I've been running the smaller 4150 series carbs for 3 yrs hoping to get a weight brake (most other heads up classes give one) but the promoter just isn't doing it, so I'm not going to limit myself anymore..... The engine picked up so much power on the dyno with the bigger 4150 C&S 1000 carb over the 950 QFT that I'm going looking for all the power there is this year.... Chassis Going to remove the Panhard bar and go with an "X Link track locator" like Pro Mod cars use. May remove the front leaf spring and convert to coil overs.... I like the idea of keeping the stock leaf spring but for some reason we have to jack a bunch of pre-load into the Left Rear coil over spring to make the car sit level and scale out correctly.... Everything in the new 3 link rear suspension is square and straight, so something in the front suspension must be causing it... and the car has always sat higher on the Right Front.... could just be a bushing or spring cushion but I'm going to check it out and then make a decision. Defiantly putting a mid motor plate in to stiffen the chassis up. There is going to be a hoop and some additional bars welded to the frame and roll cage to support this plate which goes between the tranny bell housing and engine block and it will really stiffen the chassis up. May put front motor plates in... I really like the stock appearance of the motor mounts, but a motor plate would help stiffen the chassis up even more in conjunction with the rear one. Switching rear tires. Going to run a radial tire next season. Either the MT 275 "Pro" ET radial or (hopefully) the MT 28X10.5 "Pro Bracket" radial slick (if they allow it this year). The car has worked great on bias ply slicks for a long time but Radials are so much faster if you can make them work and it's about time I stepped out of 1950's tire technology. Every top car in the class is running a radial... Will |
