Headers 1 3/4 - 1 7/8 step with 3 1/2 collectors holley strip dom intake barry grant 850 th400 5000 stall converter with trans brake 4.88 gear 31 tall tire Car weight around 3000lbs looking to shift 7200 7500 looking to run mid to low 6 sec. Car went 7.00 with mild 355. the main concern i have is cam i heard its a popular cam just not sure its what i need any info would be great thanks Anthony

The cam sounds right! I would give Lunati a call and give them ur specs. Let them tell u what they think also! Can't go wrong with to much info before puting it together!

i have built a small block before(or 2) seems you might want to check on that dur. a little more. like a little to much for that heavy a car. i would think 250-264 would be perfect for your weight, but then again what the hell do I know!!

I called lunati and that was the cam they said to use. I also called comp they said 279in 286ex at 50 dur 679in 649ex lift 106 lobe sep then i called crane and they said 260in 264ex at 50 dur 640in 645ex lift 106 lobe sep . so three pretty diff cams. Has far as et goes is mid to low 6sec pos with this combo? I know every thing looked good as far as numbers went on the desk top dyno it said 738hp im figuring 600 to 650hp.

Like I said What the well do I know
( Just watch the back of that Orange car?) never had over 260@.050
6.18@108, 3020lbs. shift at 6500(ALL DAY) every weekend

I never said you didnt know what you were talking about just trying to get some advice, and if all goes good maybe you will get to see the back of my car

[smitty]

Never know,(But like I said" what the hell do I know") But from your specs. I ran that before with a cam just like yours( I have on the shelf) and it ran fine but at a higher RPM. Went with less dura. and it ran the same number at 1000 RPM less. Lower RPM less maint. Just a thought.

[davis&keen racing]

Would you be interested in selling that used cam? Just a thought id rather get a good deal on a used one and not like that buy a new one and not like it. Whats the specs on your motor if you dont mind me asking?

[smitty]

Sure its in the garage!! it was in a 383, brodix track 1 went 6.65= changed it went 6.65 message me,
