Car lost time
I've been racing the 1/8th mile @ 6.29 to 6.32 seconds until I lost the rearend will making a run. I was finishing a run when the pinion gave way. We replaced the gears using the same ratio. When I went back out we were running low 6.50's. That trip I broke the roller off a rocker arm and it cut into a retainer. When I was was replacing the retainer I noticed that I had a broken valve spring also. I replaced the spring and retainer and went out for test and tune last night. We ran low 6.50's again. Is it possible to have lost time due to gear change even tho they are the same ratio or could there still be something wrong with my motor?
