CHI Products/quality control?
« on: March 05, 2016, 09:59:00 AM »
I know there are some engine builders on here besides just FE. My brother is in the process of updating his 434 Clevor with a set of CHI 3V 225cc heads and matching intake, 4150 style. The intake has a bad deformity on the plenum side of #2 runner, about an inch down. The air bubble/dimple is on the outside, deep enough that the inner material is almost paper thin, WD40 sprayed in the depression just runs right through. Also in the plenum are numerous chisel marks. On both heads, he pulled out 3 pieces of bailing wire from the water jackets, with a total length of 17". I asked him to send me some pictures. What's up with this?

Did he contact them about it?  New or used pieces?

I use a lot of CHI products and have never had an issue with heads or intakes either one.

Thanks Brent,

The parts are new, he is sending the intake back to the builder/distributor that he ordered them from. The builder, built the heads from bare castings so he had lots of time to inspect them. He even made excuses for CHI saying the wire really would not hurt anything. Huh?? He is kind of disappointed it the whole experience.

I can't see how the wire would hurt anything either.   I see wire from time to time in different heads....AFR, TFS, etc., although I've never seen 17" of it, usually an inch or so. 

Casting flaws are a different story.

The wire my not hurt anything but it sure don't belong left there, (quality control). Thermostat or electric water pump malfunction come to mind.

Hope he gets it resolved to his liking.   CHI is the best Cleveland head out there though, IMO......so when he gets it straightened out, he will have some horsepower. 



That little 434 made 777 hp with a set of ported CHI heads....

777 hp? Don't tell my brother that, he thinks my FE is stone age and I say his 400m is boat anchor iron, lol He is hoping for 650/700 going from his small Trick Flo heads and Holly street dominator intake, we think it was around 500/550. His pro stock class is becoming a horse power war so even at 700hp he will still be behind....

It's a 434 with about 12:1, not sure exactly, intake valves are 2.19, exhaust are 1.60, the builder is closed mouthed about it. You would think he would want his customer to know everything, but...

Did you build the engine in the picture? That's awesome, I notice what I think is a vacuum pump, does that make more power than it robs?

Yes, I built that engine.  Owner is in Wichita, KS, with a '69 Mustang.   With the right ring pack, a vac pump will add a whole lot of horsepower....definitely worthwhile with the correct bottom end parts.   This engine used ultra low tension rings and the pump pulled about 10 inches of vacuum.   My educated guess is that it added about 30-35 hp.

If your bro's heads haven't been ported, I would expect about 625 hp.  He doesn't have enough camshaft....needs about 10 degrees more duration. 

The engine above was 13.5:1, with a 263/275 @ .050" stick, .850" lift on both sides, with a T&D 1.8:1 race rocker setup.  It peaked at 7000 rpm.  Heads flowed 380 cfm with a 2.250/1.65 valve setup.  4.155" bore size with a 4" Callies crankshaft.   Quick Fuel 1000 cfm Dominator, with a 4150 CHI intake, port matched to a Super Sucker 2" adapter spacer.

I've pulled those core wires out of factory Ford SOHC heads before.  They are not a concern, IMO.  The thin casting is, however...
