After not being able to identify the cam that came in my motor I have decided to go new,but need help.Here's my setup:

70 1/2 Falcon (same as 70 Torino)
3435 lbs
3.50 rear gear , 28 inch tall drag radials
85 C6 stock
TCI breakaway conetter 2400-2600

69' C9VE 460 block
69 C9VE heads-stock
429 4u crank
413np 429 cast pistons .030 over
434.71 c.i.
4.39 bore
3.59 stroke
9.65 c.r.
Edelbrock Performer intake
2 inch primary headers
stock electronic dist
780 vs carb is the plan

I would like a good street manner cam , with mid range torque so I don't blow the tires off at the track. Looking at hydraulic flat tappet to keep cost down cause this is a budget build!! Or if someone has some used stuff that will work I am open to ideas.

Thanks for the help in advance.

Or the next smaller one would work good

Lunati offers similar stuff

http://www.lunatipower.com/Product.aspx?id=1680&gid=287 This is the Lunati that is close to the Comp 275. The Comp does have more exhaust duration (13* more), and exhaust lift, compared to it's intake lift. If you don't have the best exhaust system or exhaust port flow, the Comp cam may help bandaid it more than the Lunati. If you really want to kill some low end torque, you could go up one or two steps in the Voodoo series. Also remember at over .540-.550" of lift valve seal interference is a problem, and you may have to cut the guides down.

Supervel45 will i be safe not cutting down the guides with the cam you recommended or not then because the lift is right there? Also I have stock rockers with poly locks with they work or am I gonna have to consider rollers?

You don't need roller rockers. You do need to check your guides and seals for clearance.

Make sure to use the recommended springs with the cams too.

http://www.summitracing.com/parts/sum-3501    This is a budget cam with about the same .050" specs. as the other cams mentioned, with .503" lift on a 114 LSA. You won't have to worry about your guides and the cam/lifter kit is $118. It's just another option to consider. PS That .471" lift is a misprint, scroll down the page for the correct specs.

Thanks for all the help guys. I have finalised on a Lunati Solid lifter cam that I've had to buy from JEGS as both Lunati and CompCams do not accept non US addresses in their systems! Managed to source lifters here in the UK. Can't wait to get the parts so we can get going again.

Did you end up with this one? It was to replace the C460 right?

https://www.jegs.com/i/Lunati/638/30340505/10002/-1

Only 2 of those Lunati mechanical grinds they list.

Anyway glad you found something. Cool

Amazing after 8 years you responded. I've never seen that much time interval. Anyway your package is not hard and a Comps 262 would probably work better than that square pattern Summit stick.

I think RedDragonCobra replied to the wrong cam thread. Wink

And that Summit 3501 has changed spec.'s over the years. LoL
