'72 K5 - Greg's @MightAsWellK5 Build
- Thread starter Greg72
- Start date
This is the build description. I will improve this later. (GB)
That's why its so popular to take all that new engine technology and swap it back into the better looking sheetmetal of yesteryear!
Your just caught in tunnelvision Martin
Go play with your 396....
....
True that!I've thought about that too....
- Terminator is the new Dominator
- Oval is the new Rectangle
- 500HP is the new 300HP...
It's crazy that 300HP used to be a solid, respectable number.... But the technology has gotten SO good and the costs have gotten so much cheaper that it seems like 500HP project vehicles are everywhere now!
Some people say they wish they could have been alive during the 60s muscle-car era...I don't think they even realize that we are living I the biggest horsepower-era EVER right now!

Can you get flow numbers on the heads?
I think you can change quite a bit with a cam change, it may be worth it to use a computer simulator program to evaluate parts before throwing money down
I used a disc from 2000 to evaluate my setup.
Im sure in the last 15 years there are much better choices in that area too.
Flow numbers and valve opening/closing numbers will give some good numbers to compare parts.
Just a warning, because I'm not going to tell you how to spend your money. As you already found out, you going to have buy some additional items. You have already expected the intake and header flange. An unexpected expense is could be push rods. Sometimes these aftermarket heads have the rocker arm higher than factory to be able to get more lift.
Another problem is if the heads have a raised exhaust port. Sometimes, this raise port make headers not fit the chassis the header was designed for. You just built custom headers to fit YOUR blazer.
Warnings done and I think it would be very cool if you went to the aluminum heads.

Heres the real question.
Are your headers going to fit with a raised exhaust port like the Brodix heads probably have?

Good point. My 1st gen specific headers were built to factory heads. You already know the clearance issues I had. The Edelbrock heads likely contributed.
Dont forget that going aluminum heads also means you need to raise compression by 2 points.
According to Brodix the exhaust ports are in the stock location...that particular head seems to have been designed to be a high-performance "drop in" replacement for traditional factory BBC heads.
Still searching the couch cushions for loose change, and selling off a few oddball, old car parts so that I can convince myself that new heads are "almost" free anyway so they qualify as a "Might As Well" upgrade item.

2 points is 14% more power. See, now you're getting even more out of this. Better buy those heads!
I'm not sure if that much compression is possible with those heads (unless I leave out the head gaskets completely).

The thing is you don't need to buy all the upgrade stuff in one shot, and I know I'm stating the obvious. Getting it in chunks is a little less painful...
Not a "need" but you can get away with more...I'm not sure if that much compression is possible with those heads (unless I leave out the head gaskets completely).

You're right, although the gains from better flow will be squashed by the heat loss of the aluminum head and lower compression than what is desired for an aluminum head.
You weren't kidding there was some stuff going on in here! I'll definitely buy the H2's from you. That'll help the couch cushion fund!
I'm such an enabler. But it's not like I don't get the same treatment from you bastiges...

Pulling out the stops huh?!
Yeah!!!
So did you decide to stay with the current heads?
The "088" GM Iron heads (p/n: 12562920) are coming off.... along with the current Edelbrock #7562 (square port) dual-plane intake, and the Comp # XR258HR-13 roller cam...
If you know anyone interested in these parts, let me know. I'm hemorrhaging money these days so being able to pick up a few $$$ from the "takeoffs" would soften the blow somewhat.
