LJM97Z They are the 200cc & i'm sure there the platinums, I'm really leaning towards the XE284H or 285HL, I've ran that cam in 2 different engines & it really worked great, tuning was easy also.

When i calculated the converter, It ran a 105 that night, so it came out to 12% with a 28" tire, The tires are 275/60/15 MT DRs. When it ran 108 it came up 10%, I'm hoping i'm not running through the converter.

When i 1st. put the car together i was running a stock converter with the little cam, Tires were 255/60/15s (27"), In the beginning the car pulled really strong in high gear.

The mufflers are slow masters.

vinniekq2 If it was my car,I would use a vic jr intake,850 H.P.,headers would have 1 3/4 primaries(or 1 3/4 primaries stepped to 1 7/8),I would have 1/2 fuel line from tank to regulator, if it was driven long distance I would leave the gears you have,when you get more serious about race I would look at trans/gear combo ,,,now spend some time on suspension, alignment,pinion angle,chasis height,weight transfer(shocks and springs) unsprung weight

What intake/carb would you recommend? What about the headers/exhaust?

I don't see the intake makeing much difference, & the carb was changed & it likes the 750dp, I'm not going to stat throwing more money at it changes things, I've been told by many the RPM intake is more then fine.

I think there is a problem & i just can't pin point it.

LJM97Z It WAS trapping around 5900 with the 4.11s & a 28" MT DR, I did have the car weighed on a reputable scale at the local rock cuarry plant, I wasn't too surprized of its weight, Its a bare bones cutlass, not the fancy ones, I'm only 145 lbs., so i'm a light weight, It would be nice if the car was heavier, it would explain its slower times, Now i did calculate converter slippage & it was saying 12%, that seems a bit high, I'm getting somewhat at my wits ends with this combo, Its like what the heck, I know it should run better but it doesn't, It feels like it just runs out of steam in high gear, it just doesn't pull, but on other accasions it seems better, maybe its fuel, but i'm running a 110 pump with 8 lbs. pressure, the fuel line is all good, so is the tank.

LJM97Z The MPH in the 1/8 was 87 at best, I'm at the point of just running a 100 shot & call it good, but i'll need to re-install my 2800 stall, the 4200 just seems a bit much with a 3.70 gear.

Speaking of 3.70 gears, theres a few well in the 11s with these gears in there G bodys with 406s.

vinniekq2 Im sure the torque would be huge,just figured that there is a lot of horse power left on the table as that engine would likely roll off the power about 5800 rpm

vinniekq2 f bird,that cam looks good to me,just not sure why you would advance that small of a cam in a 400?
11-15-2012 07:19 AM
vinniekq2 The car looks like it is performing as it should.If that is your E.T, with mufflers,its actually decent.

what I would check,or look to improve:
Do you get enough fuel at the end of a 1/4 mile race?

I believe a victor junior and 850 D.P. would add another 3-4 M.P.H.

If the manifold/carb/fuel delivery added 5 m.p.h. then,,,I would use the hooker 1 3/4 primary pipe headers.
if that helped,then I would change cams after looking what helped the most

My best ET was a 12.43
Best MPH was 108
Best 60ft. was 1.73

Not all in that order. This was all with the small cam

I did run a 12.47 on a 1.87 or 1.89 60ft. though.
