Re: Ford 2.3 marine Valve Seals

If the head is stock as in not machined for teflon seals or something then go straight to Ford and buy the stock seals. There are 2 colors for intake and exhaust I believe primarily for turbo use, I just use the exh. seals on both, figure they're designed for higher temps. The intake seals are the t...

Re: Thinking out loud. Billet head with water jackets.

You will blow past $7,000 like it was a Nebraska road sign on the way to making a viable billet head. Unless you need the superior materials to deal with very high combustion pressure most of the rest is will be worse than a casting. I'm not seeing how? A friend of mine with a mold making shop was ...

Re: Thinking out loud. Billet head with water jackets.

I've thought about this many times over the years. My interest was more as a hobby project for myself to avoid the cost of the current top dog in 2.3 Ford heads - a $7000 casting from Esslinger. My idea was 2 pcs, a lower with the deck, chamber, bottom of the water jackets and the complete int/exh p...

Re: Need some 351W advice for towing

Not sure if the cam is the early or late one but if they're close then that's close enough for me. Looks like I'll try 4 advanced on the GT cam and the Performer intake. I'll keep an eye out for some rockers. That's the exact type of info I was looking for on the ign. timing. I might consider buying...

Need some 351W advice for towing

I have a later model 351W truck (roller cam) motor in my tow vehicle and am looking to pump up the low end torque and the gas mileage. Not looking to spend much money as my racing career is not what it was so spending a couple thousand to gain 2 mpg won't pay. Here are the parts I have and the parts...

Re: 2.3 Lima assembly...tips?

I do a few little things with mine that taken individually might seem unimportant but as a whole they might help and my labor is free anyway. Full deburring of crankcase. Disassemble oil pump and radius the (very) sharp edges on the inlet side. Surface grind oil pump sealing surface - the Mellings a...

Great information here! Thanks to everyone for sharing, it's sure given me a lot to think about this winter while planning my new motor.

Re: Head-Gasketing Strategy for 50psi Boost?

This joe 90 guy gets it! ARP studs might be better in many cases (Supras come to mind) but there's usually nothing more than their word that they are better than a stock fastener. How many people (besides me lol) use a stock head bolt until it's obviously a weak point? We should be asking about how ...

Re: Knock and Turbocharged Methanol

Disclaimer - I know less about electronics than, well, anyone. That being said I have a couple questions for nitro2 (Clint): How far out of range is the 2500 psi and indicated burn angle he's seeing? Do you have any other data from very similar combos? I'm assuming he is running a production car blo...

Re: Alot of timing to make it run...48

If you're looking for validation on it I will say that I have seen something similar before. Had a friend with a 460 Mustang with some of those big old dome pistons and it would only run with 60 degrees of timing. They had to manually move the timing back to get it to start in the lanes then bump it...

Re: Turbo cam LSA and exhaust back-pressure

Very interested in this, I've been wondering the same things about my 2.3 Ford. With my old smaller turbo I had a .8 TIP ratio at 40 psi, the newer BW475 is probably lower yet. Unfortunately our single cams can't adjust int. and exh. events individually like a DOHC so I wonder which would be the mos...

Re: Hi-Po Flathead Bottom End Strengthening help.

What material are those main fasteners? I hear one of the big improvements in Toyota 2JZ high boost motors is a switch to L19 (or better) head fasteners. They are only 12mm so they need all the help they can get - kind of like only having three mains. :shock:

Re: turbo fuel economy

I can add some real world experience here. Don't be too quick to discount the old Ford EEC systems. I've got a 1941 Ford Tudor sedan with a basically stock 2.3 Turbocoupe driveline. We took it on a trip to NJ once and got a consistent 31 mpg. This was through the mountains of PA with the boost usual...

Aluminum blocks and roller cam bearings

I've got a 2.3 Ford 4 cylinder and am looking into the possibility of installing roller cam bearings in the head. Have a few questions - 1 - Is there a source other than an industrial supply catalog? These are 45mm journals. Any particular brand or style? I've looked a little and there seems to be a...
