im gonna be building a 408 soon and i wanted to know what you guys think this solid roller i have would be a good cam for it or my solid mech.......12.5:1 comp, vic jr intake and heads, 800 DP, 1 3/4 headers................

Comp solid
294/250 110 lobe sep. 74 overlap 106 centerline .569 lift
or
Lunati solid roller
301in/305ex 268/272 105 lobe sep. 101 centerline .669 lift int/exh 60 overlap


i have the springs for the comp cam already...so would the extra power from the lunati be worth the money for springs and lifters???

Drag car? Street car? Airboat? Jet? Irrigation pump?? What are you going to use it for?

how high you planning on revving it? i have a similar cam (almost identical to the lunati) in a 408 running s/st. i keep it under 6800 and get by with the $120 springs on 2.02/1.60 valves. part number 73367

sure that cam doesnt have a 106 centerline?

if the converter was from a quality company, they should have its dimensions on file. give them your new setup specs & they should be able to suggest more efficient converter specs. probably 5000+ stall.
also might need more than 800 cfm carb.

It would work with the Lunati cam. That's what I would run...but get yourself a good carb. That little one ain't gonna cut the cheeze. You're going to want a 950 or better.

Basically same setup I run....but mine's an alcoholic (toilet on methanol) and I run a 'glide with a 5200 stall. Shift at 7000, cross the line at 7200. It will pull further up (never gone past 7700) but it really doesn't pick up any ET to speak of. My cam is 270-274 .700" and 104. When I ran the carb (9375 Holley Dominator) it ran 6.40's in the 1/8 at 107. With this setup on alky it goes 6-teens at 112. Judging by a friend's 1/4 timeslip that is identical to mine...that's right about a 9.70/140 in the 1/4.

To answer your question, if you must use that 4000 converter, I'd choose the smaller solid camshaft. You'll give up a little ET and MPH, but those flat tappet cams are cheap, but work great for the minimal investment. I'd say it should go some 6.60's in the 1/8 if I had to guess.

I agree Tony...that is a custom grind using comps RT series and NC series lobes. Works well in small blocks.

Custom Comp grind is $315.00 from me and I can drop ship to you. Lifters are around $350.-400.
