Project H.o. Questions

I have a new short block with the following casting numbers:

    BLOCK      3D18 = 18 Apr 83 ????
                    EOAE = 1980 Ford Engine block ????

    PISTONS  H 645 P  (.040)  Speed Pro 40 over pistons ????
                    153-03-16-A

    CAM        231003  ????  No Clue!!!

    Block was reconditioned, original crank, pistons and cam are new.

I have also obtained a set of heads stamped E7TE.

Am I on the right track for the H.O. conversion for my 87 5.0 TB?

Can I use an E303 cam with these pistons?

Can someone suggest some good reading on engine building that covers things like how to select push rod length, lifter types, rocker types and ratios etc...

Thanks.

Actually you will need a little help starting with the cam
The E cam is a roller HO cam
Your block not only has the 302 firing order, the bigger deal is converting it to a roller block. Don’t think roller blocks started to 1985.

Block has nothing to do with firing order, function of the cam only...

You'll need to pick up a flat tappet cam, no roller blocks till '85 as stated... If you can have some one degree the cam you have, it may be OK...

W/out over explaining it yes the block has nothing to do w/the F/O but if he would like to use the E cam or a any HO he would have to change it to the appropriate F/O.
I believe he stated his motor is a E0 1980 which is standard 302 before the HO stuff. I know just pointing out the obvious but he’s asking the questions and I think he could use the info.

About the cam question, ....do your pistons have valve reliefs in them? or are they just dished ( slightly counterbored). Must have valve reliefs to go with any cam greater lifting than a stock HO. ( and of course as was already stated you don't have a roller block so flat tappets only!) There is only one sure fire pushrod suggestion ... MEASURE for the length you need by using an adjustable pushrod  and bottoming your lifters at 0.00" lift on that particular valve. Chiltons engine building books have simple step by step.

That isn't always true.I had the E303 in my engine for a week with flat top pistons (forged flat tops)with no troubles at all.I pulled the cam because I thought It was giving me driveability issues,come to find out,I had lifters bottoming out and not working right.After I shimmed the rockers,all was good,but by that time,the H.O cam was re-installed.SO,the bottom line,the E303 (yes,I know my engine is a roller and the one in question isn't) did work with my flat tops (and will again hopefully in a week if the weather is decent).Tghe only way to know for sure if a cam will work is to to a PTV clearance check.
