Dare I say. Too much go! - 04/13/19 12:59 AM
So I was fiddling around with the car yesterday and have ran into something I’ve never experienced before. First off is what I was fiddling with;
1977 440 stock bottom end and 452 heads. 6a msd, torker 2, quick fuel 750( 72 front 78 rear jets) stock 727(I think)
-I set the timing from what looked like 27-30 intial to 15-17, I need to get a timing tape to be precise.
- carb from 74 front 82 rear to 72 and 78.
-Switched pcv and brake vacuum lines around so pcv runs off carb
-got about a quarter of a can of seafoam through manifold vacuum line.
Now, the reason I did this is that it was a slug even though it had no detonation with all that timing. Figured if I dialed it back I had a better baseline to mess with. After my guesstimate on timing and a rejet it ran way better. Took it out to the highway after it warmed up and hammered it. Definitely acting more like a big block but.... it was a quick blip but it acted like I still was in the throttle for a second or two after I let off. Powered right through the brakes.
-Checked return springs. Good, actually too much resistance
-No binding. Won’t doing anything it’s not supposed without load on it(in neutral)
- I’m stumped, car is still very new to me so I’m slowly working through it.
Any guesses?
