My understanding is the roller cams allow for better grind numbers. Meaning, more power.

...400 cranks. I later put the 440 block on an engine stand. For the cam, I also planned on that. Getting one of the first-series of Comp 268HE cams. I also got a Chrysler Street HEMI grind 284/284 Purple Shaft cam (the original Purple Shaft series!) cam and lifters from the old Gratiot Auto...

You have VA tied to manifold vacuum not ported vacuum then? I've rarely had OEM cam but 500rpm is low to me even if the fsm says so. 700-800 for me with RV cams. Lets the alt charge a bit better and water pump run a little faster at idle.

...to be 900ppm or "car" zddp, which is just below the old "SL" rating, which was the last oil rating considered to be tolerable with flat tappet cams. The same rating for the VW cams which ran their high-pressure diesel pumps directly off of a cam lobe. Interestingly, it seems that many gas...

...is that it is more "normal" oriented than numbers-oriented. Where "big numbers" as sought rather than something for everyday use. In looking at cams, seek lobe configurations which are asymmetrical, which CompCams introduced in the 1980s in their old "High Energy" series of cams. Where they...

Oh that's neat, didn't know refacing lifters was an option.

...low compression ratio hurt ultimate power. The interesting thing Chrysler did with their "smog" engines was to not really touch the heads or cams. The cams in those motors were a little bit larger in duration, overlap, and lift than the prior 256/260 cams of old. The intakes for the TQ can...

...polished with ARP bolts. The machine shop had to remove just over a 1/2 pound to balance the steel crank I had for it. I also used the Comp Cams EX268H (part #21-223-4). I liked the 1600 to 5800 rpm operating range because 70 mph is 1950 rpms (according to the Tremic website with all my...

I take it that this one is a youngster. Southwest Florida Eagle Cam Jeeeeezuuuss Ya click on one live link and then all you see is Eagle cams, this one just north of me shows how windy it is here today with 24mph wind and gusts to 43mph, been like this all day since I went out at 7am. .

Just a quick update for this one - Mobil 1 15w50 has ~1300 ppm of zinc and is good for flat tappet cams. I wouldn't use 15w50 in a new build though unless your clearances are on the loose side...

Wow! Great info.

...which was the normal 413/340 cam. The 413/360 4bbl cam had a bit more duration and lift, and also had a factory dual exhaust behind it. These cams can go back into 1960 or so in Plymouths and Dodges, as "Police Interceptor" engien cams, I believe. As to POWER ratings, there were some 383...

Maybe the video will help.

Those eagle cams are very interesting to watch.

...was glad to hear the heads can come off without pulling the distributor. NOT because it's hard, but i was already looking at aluminum heads and cams. If the distributor had to come out I could easier justify to myself, heads and a cam swap. I am trying to keep this built "cheap" and fun for...

That's what I've been running in my early hemi in the '34 as well as in my one-owner '68 GTX ever since the government mandated the elimination of zinc in automotive lubricants.

Will do, will check out Howard's also, thanks.

...for your car, it can PURELY be "cut and try". Each engine has its own harmonics in the exhaust system, although some are similar enough (stock cams and such) that there seems to be a huge "quiet spot" of sorts. One friend had a '70 Swinger 340 with a well-finessed stock-spec engine. He put...

...heads. I tried to order a cam from Hughes Engines and waited for months and the bottom line is that they do not have ANY hydraulic flat tappet cams in stock and have no idea when they will as they do not manufacture them, manufacturing is outsourced for these cams. Crower has a cam with...

If you opt to replace you cam, be sure to find an oil with a high ZDDP content. Older flat tappet cams need the extra additive to prevent excessive wear. Modern oils had the ZDDP content reduced to keep from trashing the catalyst. Most Diesel rated oils such as Valvoline 15-40 all fleet or...
