Thats got KB all over it! ^^^  

I shy away from engine discussion but have wondered if the given parameters could be met with a snail on a 300 I6.

That was interesting. The $800 cam is kind of the end of a low buck engine. Up to that, he hadn't spent much money.

Yes, but he made 400 hp naturally asperated on a bone stock 351W bottom end. It had 8.6 compression with cast pistons. And if you want, I can hook you up with an outfit that does custom grinds for a lot less than that. He has done it for me in the past and I have had zero problems.

That is such a neat idea . Not something for the 1 800 guys but an interesting challenge for the tinkerer/fabricator.

1st look: ebay heads that have rockers and supposedly have had a valve job, $520, Intake manifold with fuel rails and a throttle body, $574, Cam could be at least $400. That leaves custom pushrods, cam sensor distributor and a efi management system. If the efi system doesn't have ignition included, you would need the MSD stand alone controller. $475 plus coils and wiring. The total is up to a couple of grand and you can do the same hp. with a good set of heads and similar cam. I love odd job deals but this is marginal in results. I hadn't been able to find a roller cam 351 block, either. I don't know why the man choose cathedral port heads. The rectangle heads seem to be better in many ways. Am I missing something?

Cylinder heads have nearly always been the downfall of Fords. I'm not sure why, but that's how it's always been. I've been reminded of that again as I'm considering the prospects of an SN95 Mustang. At the moment they're the least expensive of all the Mustangs due to the way values fall and then rise on used cars. Fox bodies are already headed up and these cars will be next.

The 4.6 2v makes more power than the 5.0 cars, the rotating assembly can be very reliable up to 450hp, but...the cylinder heads. An OHC engine that runs out of breath at 5500rpm?

Fords downfall in performance has always been in the exhaust port . Getting a V8 to fit between shock towers in the early mustangs etc was the reason for that.

Seems like the engine program is getting a bit complicated?  I understand you are heavy in the cypher mode.

the exhaust ports on my Ford  inline 6 engine 1978 200 cid were quite small.  I put  some effort into them for port and bowl work to help flow.

Progress is about to begin. I ran to Garden City this morning and picked up enough steel to finish the chassis and bed frame. The older stock was priced very reasonable. The new stock was 2.5 times higher than it was several years ago. The important thing is they had the inventory to fill my order. My plan is to have very little inventory of steel left when this is done. My lack of storage space has a lot to do with that plan.

[idrivejunk]

Hot diggity!    

Happiness is bringing home exactly what you went for.

O&S worked a little on this today. The rest of the steel is moved to the garage and the 302 was brought in and disassembled. I haven't measured everything but there was no glaring problem. The worst thing I see was a shortage of oil changes.

[kb426]

O&S was busy today. I finished stripping the block and have all the steel parts vatted. The block and crank all measure good. There's 1 thou taper on the cylinders. As near as I can tell, this is a 87 or 88 mustang engine. It has forged pistons and all the casting numbers correspond with the info I have. Now it's time for decisions. I have to decide how much money I want to spend. 400 hp. is possible with a stock stroke engine with really good cylinder heads and a streetable camshaft. I can just freshen the engine and spend very little or step up by around $2500 to double the HP.

[kb426]

Minor update. Pistons are cleaned and the heads and valves are cleaned. I ordered a bunch of parts today but not enough to finish the engine. More decisions ahead. It's been quite a while since I had to clean ring grooves. I've been using new pistons on my engine builds. It didn't take long to remember how tedious it is to do that. LOL.

O&S finished a few tasks on the block today. I had a soft plug in an oil galley that was stuck. My efforts for removal had failed so far. I thought about making a tool to use as a puller from the back side but decided I would try something different 1st. The plug is .5" od. I drilled it and tapped for 3/8. That was a starter. I ran a 7/16" coarse thread tap through it. I took a bolt with a nut and washer and threaded into the plug. I tightened down the nut and it removed the plug. Mission accomplished. I dingle berried the cylinders. Then I threw the block back in the vat for about 15 minutes. It's clean enough to be a good start. I have cleaned cylinders by hand before and never thought I got them as clean as they should be. All the abrasive grit is our enemy for the parts having a good chance to a long life. Slowly moving forward.

I was taught to wipe the bores clean in the opposite direction that the hone was spun . Always did that in the hydraulic cylinders that I machined
