that sounds better. with the 406 it will move the powerband down to around 6000. and it will work with your converter. If you get it on a 180lc it will move the powerband down and give it more bottom end. great if racing on slicks, not good on treet tires.

Thanks for the help that would probably be best with my cast bottom end small heads and 3.73s. I will be changing the converter I am putting a j.w ultrabell on it a 10inch converter is the biggest that fits. I am going to have my driveshaft checked tranny shop says it could be out of balance hopfully with this and your suggestions on the mounts I wont have no problems

I ran solid cams for years. If you cant afford a roller a good solid is great. Make sure you break it in correctly and run race or diesel oil only in it.

I was told that I need to change my pinion yoke and tranny yoke to run a 1330 u joint instead of the stock 1310 I dont really think I need all that for what I have even with the cam and converter change. I will run drag radials but never slicks and leave on a footbrake I think its overkill what do you think

run solid joints and make sure that they are installed right and they should be fine.

If you are ever going to run nitrous get one on 110-114 lsa. cam 4 is going to need alot more converter. cam 2 should have a nice wide powerband.

what do you think i can gain by changing the cam? I taiked to A guy who has the same combo as mine in a 80s regal only real differances are cam he has a 504/525lift 233/241dur.@50 276/284adv. his car ran 11.82@115 1.71 60foot his car is lighter by about 5-600 pounds. He said he dont care for vacuum secondary carbs he thinks with carb tuning or mechanical secondarys and tires I can run low 12s-hi 11s without spending all that money Ilike the sounds of that do you think it will work.

slicks, a better converter, and tuning will get you to low-mid 12's. 11's will also take a manifold and cam. just my opinion. you have to remember 600 pounds is 6 tenths of a second. your friends 11.80, plus 600 pounds, is now a 12.40.

If it was me I would put tires and a good 10 inch 3500 stall converter in it. take it to the track and tune it to the best you can do and you will be suprised at how quick it will go. I would bet that 12.2 or faster is possible.

do you have air bags in the rear? they will help a stock a susp chevelle. your 60' times are to slow, it should be a 1.8 or less. the tires and converter will fix that. again just my opinion.

I agree with everything your saying. I am going to get a set of M/T drag radials and a converter try to tune the carb I have not played with it at all or timing at the track to see whats best I think I will fix whats broke tune what I have get it rite and go from there. I am also getting a good set of lower control arms and air bag or ajustable anti roll bar. I already have uppers and drag shocks front and rear. I thank you for all your help I dont have to many SBC friends I played with late model mustang til a few years ago
