Maybe... I can make sense of this one. You blew the motor in your pre-vortec truck, and you want it back on the road. Vortec heads have a specific intake bolt pattern, and you could screw a lot of customers over.

Besides, Vortec heads are only really all that good for people who want a cheap head to make decent power (250-350 hp). After that, you're back to the original style bolt patterns and MUCH better heads.

Well, ya wouldn't be able to advertize it as a REPLACEMENT engine, but as a cheap, 300 hp performance engine with vortec heads. How is that going to screw anybody over? ANY engine with vortec heads is going to need a vortec compatible intake.

I think a 300 HP vortec head SBC long block for around 1500-1700 bucks would sell like hotcakes. They'd have to put an extra shift on at the plant down in Mexico!

There is a market for people who want an engine that will accept all the stock stuff, so they can bolt on and go. When smog is a concern, changing the heads could have a significant impact on what original components can still be used.

GM Performance already makes an engine for them: 10067353. What I'm talking about would be a different engine, advertised to a different buyer. Pipe dream, anyway, they aren't gonna do it just 'cuz I want them to. They may have some good reasons for the decisions they make, but as I get older, I am not so sure. More and more, lately, it seems like the entire world is run by knuckleheads. Maybe it's just me getting old. LOL!!!

i'm actually looking at that motor. i have a really mild hydraulic roller cam and the retro-fit lifters, with the cam having similar lift and duration at .050" specs. i like the hydraulic roller over a flat tappet cam for the much decreased wear as much as for the lower parasitic losses. i'd go with the Keisler 5 speed conversion but i cant make myself spend that kind of money right now. I chose a 200R4 over the 700R4 because the 200 is the same length as the TH350 AND the driveshaft yokes are also the same.

i guess i should have mentioned that emissions inspections arent a factor, no visual inspections either in SC, but with the self tune injection it ought to be pretty clean anyways.

And the wierd thing is that all the parts are right there in the bin!

I've assembled a couple of these from the shortblocks metioned...smokin deal for a great engine.

I'm an engineer... I agree about the knuckleheads, not too many people think I'm old either!

Sorry, I thought you were saying to replace the 7353. I agree. A 7353 with iron heads would be an interesting solution. I'm sure someone has done a cost/benefits analysis on it... maybe someone's afraid it would kill too many ZZ4 sales? Same power for $1500 less.

I can't even imagine that it's worth the $$ to keep casting iron heads, but I'm not a manufacturing engineer.
