It's been a while since I've posted, busy with school and work. I finally was able to buy a Daily Driver that was good on gas, a healthy 92 Escort Wagon. I have been wanting to build a engine ever since I was little and now my 95 GT is parked. I've been doing research and I want to build a 347 stroker. I want to do all the work myself I can, except machining which I might be able to just hone since the engine was rebuilt about 3000 miles ago. The biggest question is about the head selection. I'm a college student and don't have a high budget. Can you port and polish stock heads or will I need to go to a TFS/AFR head? This car will not be a Daily Driver just a weekend ride. It doesn't have a specific time to be done. I would like to get around 350-400 RWHP. Also anyone know any good brands of micrometers, dial bore gauges, and dial indicators that are not ridiculously expensive? Any advise would be greatly appreciated! Thanks!:)

You can port stock heads. The guy I bought my shortblock from ran 10's on stock ported heads. On a stroker they still may not flow enough though. Someone else will chime in

You can port the stock heads but they'll be too restrictive on a 347 stroker and you'll need aftermarket heads to reach your HP goal.

I would like to build my own engine though. I might be getting a job at a speed shop after school and need to start building some so its not new to me when I start. Any good heads on the market that are not stupid expensive?

The TFS 190cc FAC heads would be good out-of-the-box heads for a 331/347 stroker and they're reasonably priced too.

Thanks! Sorry I was out of town, that's why it took long to respond.

Another question if anyone sees it. I'm getting the Eibach Sport-System-Plus suspension kit also. I want my car to be a good handling car around turns and on the mountains. Would a 347 still be a good engine or would a beefy 306 handle better around turns? Or does it really matter?

The 347 may actually weigh less, depending on what rotating assembley you use. Don't use the stock heads. You'd make more power with a 306 and good heads, than a 347 with stock heads, no matter how much they're ported.

A stroker engine is not cheap man. You can only do so much. After spending what, $800 for lets say an Eagle stroker kit, you'll need to take it and the block to a machine shop and get the block bored out and honed and notch the skirts for clearance. Also they will need to balance the rotating assembly. This includes the flywheel and balancer. The reason anyone builds a stroker motor is to make more power and to do that you need good heads. AFR 185's would work on a 347. A really good deal on a set would be around $1000. A set of assembled GT40 heads can be had for $400. More if ported but even then their not good enough for a 347.

Now, a nice fresh 306 with those ported GT40 heads and a good intake with the right cam will get you in that 350HP range. You can buy a new 306 short block for $1000.

You could also take your 302 to a machine shop and have them bore the cylinders out .030 for you and attach the new 30 over pistons to your connecting rods for you as well. Then you assemble the block yourself. They would provide you with the right oil rings and bearings too.

Sorry its been a while, I got real busy. Update. I installed full Eibach sport kit, new tie rods, and ball joints. Resealed my injectors and bought Sumitomo 275/35/17 HTR Z 2. Keeping it a 306 until I get out of school and have the facilities to build a engine. Going to the junk yard soon to pick up another set of gt40 upper/lower and heads and polish and gasket match them. Possibly get the heads ported if I can find a decent speed shop here. Buying long tubes, o/r x pipe, and m80 mufflers when I get my tax return in a few weeks.
