Lets talk engine packages

Next one off track gets an infraction and a one week ban--back on topic--

PLEASE!!!

So according to their data, I can gain 4-8 HP all the way through the power band by swapping to 1.7 rollers on a stock cam, not to mention the other added benefits like a cooler running engine (due to less friction.)

What about the spring size?

 

[chriswells78]

Well, spring size anyone, I'm putting my order together...

 

[chriswells78]

I filled out an on line cam request from Comp Cams and this is the cam they recomended:

PART NO. 35-510-8

I just looked this up...

http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_103408_-1

$711.99

only $175 for an E cam.

So what are the cam specs of that, the Jeg's site was no help?

That is cam, lifters, timing chain, & assembly lube. All stuff you are going to need.

For a new engine or high mileage I'd change lifters. But I would not buy new roller lifters if the mileage isn't high. I don't want to pay more than about $200 for a new camshaft, and $50 or so should buy a true roller timing chain set.

I fortunately have the used cam which I had bought new for my 91 302 HO engine build. I think it will be a decent first cam for my project, I've already paid for it($180 then).

Hunt around for other cam recomendations, surely something else is more reasonable than $261.

 

[CDW6212R]

So 208 intake duration and 216 exhaust, with a 112 lobe separation angle. I recall that being a cam that I mentioned sounds very good. The Ford cams are all over 220 duration on the intake side, which is way too much for our heavy trucks with automatics.

Mine is a 212/222 cam which may be a hair more than I need, but mine will be a testing baseline engine first. Regards,

I'm winning on an E cam on Ebay right now. People here have done it and it works. I'm also looking into 1.6 roller-rockers, I'm going to do the same set up he did for his with the 1" intake spacer, 1.6 rollers, I'm hunting valve covers now.

I would like to do springs too while I'm at it. Unfortunately, nobody knows what size the springs are.

 

[CDW6212R]

Does not Summit list a replacement spring for an Explorer 302? I would suggest doing the springs also, those should be done every 100k or so if possible, just like timing chains. Regards,
