He has a 65 Old with a pretty decent 455 in it. I ran a 13.2 @ 106 with my 360. Now My 408 is damn near done, and Im kinda worried my car wont hook. My 60 ft times were terrible. 1.99 was my best, Its a 4 gear car, and the M/T et drag radials werent hookin at all. Someone told me my Summit brand shocks are too short and thats my problem. I have SS springs, and a pinion snubber, and I had the air to 11 psi. I was told thats too low. Any ideas here. I did buy the Xlong mopar performance shocks, and they are only about 1/2" longer than the summit shocks. I know Im puttin more HP out with my 408, he might have me on torque. But I would hope my car will run 12.50s all day long. Randy who sold me my B1bA brodix heads said it should do that with 1 plug wire off. But I have to get my traction issues figured out, and the summer is dwindling fast, and Im still waiting on TTI for a #7 header tube.

Any pointers here would be great. I have contemplated buying the caltrac bars, and running them on the SS springs. The bad thing here is I dont want to put a cage in my car. Its a street car mostly, and I hate the bulky looks of a cage. What times require I run a cage?

Thanks in advance guys. Oh im running 3.91 gears...

KAsey

NHRA is 11.49 or lower.

Hell Id be VERY happy with 12.50s so Ill be good. I just am scared of it not hooking. I hate slipping all over the place outa the gates.

Do you have any of tires you could try??

Well right there's your problem. I'm sure that'll crank some people up.

Do ya mean different brand, or slicks?

I love rowing gears, Always have, but I dont think thats my issue. Id like someday to build a decent 904 for it, but then I hate to de-convert my 4 Speed car. I spent a lot of time and effort switching this car to a 4 speed.

Yes. Like some QTP's.

R those Hoosers?

Yes.... Hoosier Quicktime Pro.

You need more air in the radials for them to work, start at 18 psi and go up 2 psi till it slows down. then lower 2 psi till it slows down. You will find what the tire wants. Mine was 18psi..Loose the snubber and clamp the front segments of the springs. The MT radials need some heat into them to hook. How are you doing your burn out? dont sound like your getting any wheel speed in the burn out to make any heat. If all else fails just leave easy and im sure you will at least get a 1.7 60' time....Phill

Thanks Phill, I questioned my Burnout also. My car really wanted to walk to the left, and almost into a guard rail, and I never got a chance to try the other lane. I did a good burnout I thought, good smoke, and held it there for a while but Im honestly a little new at the track, only been down it about 4 times with this car. Now with the new engine almost in it, I want to straighten any potential issues beforeI run it again.

I know a new engine making more HP is just going to make spinning a bigger hassle.

Kasey

How much HP are you hoping to make??

Well, Id love 500, I was told it should make 535, but I doubt that. I cant afford to dyno it, so Im just gonna have fun with it. Its got Great heads, they were on a 416 that made over the 500 hp mark, and Im just runnin less cam that he had. I have 10.8 compression, solid roller cam, K1 crank, Child track master rods, Hughes main stud and girdle set up, and toipped off with a Quick fuel Carb thats a 750 slightly opened up from them. I bought the carb second hand and was told its an 800ish cfm. Ran good on the 360, might need jetted up a tad on the 408.

Kasey

all the posts ive read the MT's like more pressure than that, 16-20, i'll be in the same boat here soon testing mine

What did the heads flow and whats the lift/dur on the cam?? 1.5/1.6 rockers??

i've got about the same 360 setup but an auto and 4,400 stall. my SS are not modified and i run a pinion snubber about 1/2 " off the floor. i thought my koni gas adjust shocks were going to give me trouble but it hooked fine 1.66 60' 12.22 et. try adjusting your snubber or removing some rear spring clamps before going to longer shocks BTW i did try the MP long shocks on the street and it hooked worse on the street.

My 325/50 mt et streets hook pretty good on the street at 15psi. 4 spd car here also. The biggest difference in traction for me(on the street, not that I would test traction on the street but you know how it goes ) was pinion angle...

106 should be good for low 12's I'd think. And 11lbs is WAY to low. I ran my ET radials at 22-24lbs. What are you lauching at? Do you have a line lock? It can be hard to get the tires hot in a pedal car w/o it. You might want to get a pair of 90/10 front shocks or you could always go old school and pull a set out of a /6 car at a junk yard. Plenty of fast cars out there on just SS springs I wouldn't drop the coin on t he cal-tracks.
