Re: Question on Ford 3.4" '363' Crankshaft

As long as the throw surfaces and fillets are at least .250" thick everywhere; you should have no strength issues. Thanks Guys! I hope it's 0.250" thick everywhere. No way to really tell. lol Was looking at the packing slips, and I bought most of this stuff 10 years ago! About the only choices at t...

Question on Ford 3.4" '363' Crankshaft

Several years ago, I started piecing together my 363. There were limited internally balanced 'over the counter' cranks available, and I got the 4340 Scat. It is a 28 oz-in crank, but I had lighter weight Oliver rods and light Mahle pistons. I noticed on a lot of cranks, that from the side, you could...

Re: V-8 Ranger

There's a model year cutoff with Rangers... where some kits fit the early trucks, but not the later ones. You need to know the year of your truck, the cutoff... and then you can do your research. You're way ahead if you can get rid of the stock twin-I beam suspension and steering box. Putting a mode...

Re: 1400 hp Big Chevy combinations

Cheap, Fast, Reliable... Choose Two.

I haven't read the replies, but there's a chance he could do it.
He would have to be really smart about finding good used parts, then spray the LIFE out of it.
It would be a bomb, and that $6k probably wouldn't last very long.

Re: 100 Octane Pump Gas by 2020?

The IDEAL combustion of any hydrocarbon is: HC + O2 --> CO2 + H2O The actual combustion of any hydrocarbon is: HC + O2 --> CO2 + H2O + hundreds of trace amounts of obscure hydrocarbons. In fact, what comes out of a tailpipe often does not resemble what goes into the engine. That's what was emphasiz...

Re: Sbc 400 vs 415 vs 427?

You said you had ported Profiler 195 cylinder heads. The build BLOCKMAN is referring to, used AFR 220's. I originally said going much over 400ci was approaching the law of diminishing returns without going to a head that spreads the pushrods for bigger ports. That depends on your application. If you...

Re: Sbc 400 vs 415 vs 427?

I don't think there's a whole lot to gain by going over 406ci using standard 23 degree heads with the intake ports in the stock location. If you went 18 degree, or even a 23 degree head with the pushrods moved further apart... you'd better be able to take advantage of the extra displacement. These h...

Re: 302 Ford manifold selection

This is going on my 363. It's a seriously ported Super Victor done by Mike Curcio at MCRP. He was known for doing good with these. The widened corners at the plenum opening are supposed to be for fuel drop, as he called it... or mixture distribution. He told me where he was going to break through ah...

Re: 100 Octane Pump Gas by 2020?

NOx is still a bad thing. An engine burning at stoichiometry will produce nothing but water and carbon dioxide with perfect combustion. With imperfect combustion you get enough free oxygen and NOx to break down into free oxygen to mix with CO and HC in the catalyst. Either way the combustion has to...

Re: Plastagage versus bore gauge

In a pinch, or to get a quick reading without having to take several measurements... I've installed dry bearings on only two journals... such as #1 and #5... tightened the caps... then placed a standard dial gauge on the crank next to the bearing. All you do at that point, is lift up on the crank, a...

Re: 100 Octane Pump Gas by 2020?

OEs are looking at other ways to control detonation. Variable compression, water injection. . . It isn't just about detonation, but NOx pollution. And with direct injection NOx is largely reduced "naturally", allowing for smaller engines that make acceptable power via higher compression and turboch...

Re: Plastagage versus bore gauge

I read about all the 'evils' of Plasti-gauge... Bought quality mics, practiced and practiced using them until I was consistent and found myself proficient at using them. Still, I didn't build engines for a living, so I would check myself with Plasti-gauge. Once I got good enough with the gauges, my ...

Re: Any HP test with Spintec mufflers?

Motortrendondemand did a dyno test of several types of $40 mufflers on their Engine Masters show. The test engine was a Ford 351C stretched out to 408ci making just over 600 hp. The 'straight through' mufflers cost very little power, if any. The chambered mufflers cost quite a bit, and the turbos ev...

These heads are closer to 130cc’s intake port, 1.78/1.45” valves :lol: The bowls are tiny, but they are thin where I really need to open them up, so I am am extremely hesitant to open them up any further.

Re: Gains with lift beyond the point of max airflow?

Camking, Appreciate the response, going back to Travis original question, I still stand by my comment of increasing the ratio in his application with those heads won't net anything obvious in my opinion. The people actually doing it have proven otherwise. If an engine is cylinder head limited, you ...
