Hello all, new guy here, long time street rodder.

In one of our builds we have a ford racing 351 (M-6007-C351), the one with the 362 hp. We are looking at making a few upgrades and would like to see if you guys have some ideas that we haven't thought of yet.

We haven't made any changes on it other than a little hotter ignition, the carb is a Holley 750 hp.

We thought about forced induction of some kind, but most supercharger/turbo motors seem to like automatics, and this one has three pedals.

Injection is still up in the air, but we have heard mixed emotions on injection kits these days.

We were thinking more along the lines of heads, cam, intake, different carb.

Any ideas/thoughts?

Thanks!

Your question is about as open ended as it gets.

Not anywhere near enough info as to what you are able and willing to do, to spend, what your goals are etc.

Well we build motors and street rods, so that should clear up abilities. We can pull the motor if we need to, but I'd rather leave it in place. I don't really want to get in to the short block (other than a cam swap) because it's so solid, I'd rather do all the upgrades on the top end. Budget right now is pretty high, I don't have an exact dollar amount, probably somewhere in the 3-5k ballpark. Goal is an extra 75-100 ponies.

I'm going to do heads and cam for sure. It has gt40 heads, hydraulic cam m-6250-A332, and 9.0:1 compression currently. If I can get some specific suggestions on head and cam recommendations I sure would appreciate it.

What I'm not so sure about is induction. I'm totally open for suggestions on that. It currently has the dual plane performer rpm intake and a Holley 750 hp carb.

Thanks!

You have many choices depending on your budget. AFR Renegade 185's and camshaft will net you 100hp. The TFS twisted wedge are another good choice. You may need to notch the pistons with any of these heads. A more budget approach is a good 3 angle valve job on those aluminum GT40 heads plus camshaft swap which could net 50hp or so. You could also mill them .030 if they are the 64cc models.

I'd go with 225 high ports and a port matched vic jr intake.  Get a custom cam ground, and it'll put a smile on your face.

You need more carb, too.  Again, a custom carb set up for your specific combo is the best choice.  For efi, I can recommend holley.  I have their HP system...I had some problems with hardware failure, but they finally made it right.  It's fairly easy to use, and the tech guys can help if you have triuble areas.

Sure TFS 225 high ports would be nice but would eat all of his budget and still need different pistons along with a ported victor jr intake and etc. I think they are a just a little over kill for his needs.

This is the first I'm hearing of high ports requiring special pistons.

The hp's are 2500...how much are afr 185?  If there's room under the hood, a super vic will work instead of cleaning up a vic jr.

My philosophy is it's better to aim above your target

High ports have always needed specific but off the shelf pistons from day one.  The AFR 185's $1600-$1700, the TFS 170's less than that. It does not appear that he needs a cylinder head capable of 700hp  when he is working with a 9:1 stock 351W short block. Plus to make those 225 work to their potential now you need shaft rocker arms and custom headers which is more money. Over kill is not always needed or affordable.

It's 9:1 now...that can change.

You don't know his needs, as they haven't been stated.  You also don't know that custom headers are required, as we don't know what vehicle it's going in.  Lots of assumptions going on in here.

Last I heard, high ports are inline heads...still not seeing the piston change.  Trick flow lists them as requiring inline style pistons or HP specific pistons. 

What happened to the "big heads DO work on small engines" mentality?  With the same redline and correct valve events, the 225 high ports will outperform smaller heads on a 351...right?  Who said you have to max it out with shaft rockers, etc?

I posted what I would do.  That may or may not be ideal for someone else.

It has to be streetable, we won't be racing it on a track ever. It's decent now with the power we have, we just want a little more. It's a '60 F100, so tons of hood space.

It's a 362hp engine. He said that in his first post.

He said he wants an extra 75-100hp.

His needs are known, no assumption was made. If you didn't know his needs then that because you were not paying attention.

He said $3,000-$5,000 budget!. Yes the high ports take specific pistons..........a mild .500 lift cam may clear the pistons if they are 2.02 intake valve, but maybe not. For sure not 2.080!!!!!. Standard bolt pattern headers will choke off the exhaust port so now he needs headers, plus the exhaust ports are raised!. Shaft rockers make life so much better on high ports but its obvious you never worked with them. Sure stud mount rocker arms can be used but its ugly.  Big heads on a small engine can work great with the correct camshaft but are high ports needed for 450hp?.............heck no.

I don't think you need to spend alot of money to gain the power you want. The best route would be a AFR 185 or TFS 170/190 as cast twisted wedge heads plus the hydraulic roller. Then sell your GT40 aluminum heads for what ever you can get. Not too hard or expensive to get 450hp.
