HI all. What I have 545 scat stroker, RPM heads (75 cc If I remember correctly ), intake and Cam. I'm having to pull the front to check my timing alignment. Tho the cam is used (mine) slighty with no ware that I could see. if I do have to change it out.. what would be a better cam for MOre power /TQ with the parts I have? I did have to clean up the heads they were crap from the Factory had gouges in the ports. Don't think I'll buy Edelbrocks again I expected better and didn't notice till after I clear coated the outsides.
thanks
Tim

The edelbrocks are nice heads . Some basic tidying up they do make good power and torque.

What is your current cam , bit hard to evaluate without knowing?

HI as I stated in the first post its an Edelbrock RPM cam , heads and intake..
I was very un-impressed with these heads they had big gouges in the exhaust ports I had to clean up and spring pockets were crap and had extra casting crap around the pockets.

What is the engine going to be used for and what compression do you have. I would get with one of the guys here that does custom cams and let them grind you a cam

HI Mostly street some track time I think its around 10.5:1. Its in my 64 IH pictured in signature, 4,500 Lbs. I believe. When it was just a 466 it ran 14.5 1/4.
Thanks all

Transmission, gearing and tire diameter are just a few important things to know.

Depends exactly what you are trying to achieve. That is not a lot of cam to feed 545 cubes, but then the truck does weigh 4500 lbs so got to be a bit realistic/conservative.

For the heavy truck , 3.5 gears and tall tyres its probably an okish cam .

What torque converter ? That will make a huge difference also.

Ive used several sets of Edelbrock heads and have found the ones I got to be nicely finished off

Hi rear is 3.55 i thought 28" were considered small tire? I have the RPM cam in it now why would I go back to the performer? OH stock stall converter.
thanks

I have some Edelbrock CJ heads, and they were rather rough straight out of the box. They had a lot of casting flash in the intake ports, and some pretty large and sharp burrs where the machining left off at the rough casting.
But about an hours worth of port matching and cutting down the "blob" of casting flash on the port walls, made them righteous! Cool
The top of the valvetrain area was nice as cast.

You provided no cam specs , I googled to try figure what you had confused , did not suggest to go backwards at any time

Stock stall , yeah nah that'll be killing it down low . Up around 3000 as a minimum would be my choice

28 is a relatively tall street tyre.

EDIT : just checked that link again says Edelbrock Part # 7167 Performer RPM Camshaft ?????

A 545" with 3.55 gear and 28" tall tires and being a truck should melt the tires at will - even with a 2200 rpm stall converter.

This must be the one......................Camshaft Specs:

Thanks everyone ... But why is everyone hanging on to the CAM I have and trying to figure it out GEEZE Edelbrock only makes ONE RPM cam for the 460? I didn't think I'd have to give its specs. I thought someone would have already done cam changes and had some kind of idea of a better cam for better using the power of a 545??
As for stall I read somewhere the you can increase the stall of what you have by adding Cubes and HP/TQ and I was going from a 466 to a 545 so I thought I had it covered..
thanks

The reason why is because not everyone has the cam specs memorized!
When we see what the specs are, then we have the info to base a comparison to.

No problem, Tim! This is what we are all here for, to help each other out with technical questions, ideas, suggestions, and support!
We all love the big block Ford engine, and ultimately, we all want to see it at the top of it's game no matter what type of service it's put into.
Have fun and enjoy the site, it is just as much yours, as it is anybody's! Cool

Yes exactly , I went looking for a link to try to piece together exactly what your whole combo was..

When you take the whole combination of the weight of the truck and gearing etc it's all got to match somewhat . A little conservative can be good in this case.
I've seen a few F trucks that guys put a "RACE" style motor that would normally be nice in a lighter street car , in a heavy truck the thing was a pig.

You are kind of correct to point in regards to stall speed . To a point the converter may stall a tad more if it is a GOOD quality converter . Start throwing a lot of torque at a stock converter you get to what's called " Blowing Through the converter" That's where the converter no longer can lock up and drive correctly and starts to slip , so then if the % of slip increases you feel less power

Hi Not really a stock converter just stock stall .. tranny was rebuilt with extra clutch disc and shift kit a few years ago.. when I built it as a 466 with performer parts.

The reasoning is simple, if the cam is the 234/244.
That cam you have is probably to big for the 470 in that type application and may be more correct in the larger engine.

I am really sorry if you think I interfered with your thread by voicing a statement you didn't like, (you make a big deal about 4 cubic inches; really) ... you can rest assured that I will never interfere with another one.
It seems you already know more about what is needed for these engines for mostly street at 4,500 pounds, than I could ever be of any help to you.

I think i'm out also .Prob wasted more time here than I should . Should of given up after I went looking for the cam specs above .
This is going nowhere except Tim appears to get annoyed when we don't say what he wants to hear. Good luck mate      Rolling Eyes

4 cubic inches ???? How is a 545 cu. in. only 4 cubic inches different than a 470?? I don't get it I've never had this much trouble with a thread. I'm done as well.. apparently no one knows..
Thanks anyway

…….and here is where it all went to shit!! a little bit of humility goes a long way brother. Let me tell you something... you cant go around here looking for answers when you don't want to at least help yourself and then getting an attitude about it. these guys on this board ARE the BEST when it comes to the BIG block FORD. these guys owe you nothing. A little respect goes a long way.
