Which cam do I need?

[JW1965]

I want a mid range cam, but I don't understand the numbers...

I need something that is dependable and can be driven in traffic (if needed), but will also will be able to cook somewhat. I know that I can't have the best of both worlds (i read the tech article @ classic inlines).

I will appreciate any help!

JW, what size engine do you have?
Also what transmission is in your vehicle?? Bill

 

[JW1965]

I don't know why I didn't mention that!

I have a stock 1965 200ci bottom end, a rebuilt 1980 head, Holley 2bbl 350 cfm carb, upgraded to electronic ignition, and a dual outlet header.

The drive train is compiled of a 72 maverick 8" rear end (or whichever the 4 lug came on) and a ford 3.03 tranny with adaper to a 2.77 bell. The gears in the rear are very high (2.79) but I will be switching soon to a T5 4cyl transmission to hopefully bring down the overall ratio. It is too expensive for me right now to spend $800 on a 3rd member with lower gears.

That should give you a pretty good picture. This is my first project, so I am open to hearing suggestions.

Is the carb via an adaptor (2 into 1) or direct mount? Any head work or oversized valves (currently or planned)? Compression ratio (currently or planned)?

 

[JW1965]

the carb is a direct mount. we have custom made a mounting bracket that is between the log (milled flat) and the carb. the head as i said is a 1980 with 302 springs and stock valves... I'm unsure of the compression ratio (I don't know how to find it, I'm still learning) but I know that we milled .070 off of the stock 250 head.

JW, i believe the 264 camshaft with a 110 lobe center would be perfect for your application. Since you have stock exhaust valve size another choice would be the 264I-274E @ 110 lobe center.

Either cam will bring your engine alive. Bill

Ditto, I'd recommend the 264/274-110

Not to steer anything from Mike, but Comp Cams makes a nice 260H cam for a mild daily driver. It's what I'm using and I'm happy with it. Nothing crazy, mostly just more lift so the engine still runs smooth without much loopyness (is that a word?).

Granted, if Mike had cams when I bought mine, I would have gone with one of his instead.

I think it's lopeyness. Loopyness has more to do with the way most of our brains run when we get around cars.

I hate to steal a thread but while were talking cams. are there any good book's manuals, or tech materials you would recommend concerning cams and how they affect performance/drivability. I just keep hearing alot of number being thrown around and would like to understand what cam to pick under what conditions. I plan on doing a complete rebuild and would like to beable to figure out what cam i need for my finished project.
