I agree, very good info here. Thanks everyone. Now, more questions.
I may have the chance to pick up a 1997 vortec 454 complete engine, runs good, includes the FI system (intake, injectors ect.)
Are the vortec heads any good? What about the blocks?
It's only 500 bucks. But I think I'd only end up using the bottom end right?

As for the overdrive ratio, I don't have the trans yet. I'll be getting a whole kit from Keisler.
I see the hp numbers climbing in the other posts I have the same problem. "Ok, if I can get 500, why not 575. Ok, why not 650, ok, why not 700?" Too funny!
It's hard to keep it in check at times. But needless to say I'd take as much as I can get for power.

Block will be fine but the heads are junk for making any power.

That's a good deal since a brand new Gen VI block goes for over a grand.

I didn't know a new block cost that much Todd. I am going to drag home the truck my engine is still in this afternoon. I should have the motor out and torn down by tomorrow evening and off to the machine shop Monday to have it checked out. I might pick up the vortec motor Monday as well just in case. If I don't have to use it now, I'll have a spare that I might build with higher goals somewhere down the road.
Now, someone stop me if I am going about this wrong. Is the '97 block and crank/rods better to use than the '77 I am about to tear apart?
I'm at a point where I can start on either one (once I buy the vortec motor Monday) so if anyone has good advice on which one to build please tell me now.

I really want to express my grattitude to everyone who has responded to this thread. You all have helped me a bunch and I really appreciate you taking the time to help me out on this.
Eric

Hey Eric. I would wait to see if the truck engine is worth before buying it.
That's 500 bucks, or should I say, more horsepower towards your '77 engine, if it worth it of course.
GOOD LUCK!

Good point tones. I was thinking since I need to have either one checked out before I can build, and either one will cost the same to have checked, which one would make a better foundation for my project with all else being equal.

Thanks,
Eric

If you were planning on a mech fuel pump there is no provision on the gen v block.

That's a gen VI and it does have the provision.

Ok, the '77 block seems to be ok. I'll drag it to the machine shop tomorrow and have it checked out.
I have decided to build it as a 496 and push the power goals up a bit.
I'd like to see 550-600hp/tq out of it. I know this will require some changes in what parts I can use from the stock short block. I'm guessing the only thing I will re use will be the block itself.
So now I am open for ideas on which crank, rods,heads,cam.....
I will be going to a hydro boost set up for the brakes. I will also be going with a 6 speed from Keisler so I shouldn't have to worry about the trans being strong enough or vac for power brakes.
The choices on cams and heads is making my head spin.
There has been talk of AFRs ,Brodix, Trick Flow, Edelbrock and GM heads. All of that was based on a 454/468 build at 450 hp. And with power brakes. Now things are changed all the way around.
Can these power goals be reached with a hyd roller cam?

I keep seeing stroker kits everywhere for small blocks but not much advertised for big blocks. I have looked at chevelles.com and there are alot of ideas there. But I have kind of developed a trust for the opinions here. Nothing against the other sites at all. Please don't take that wrong if you are members of both.
Thanks,
Eric

I guess I should thank (or blame ) Todd for posting his dyno video. That got me convinced to go with a stroker.
And the video of it running through the roads.

Todd, if you had to do it over with your engine, would you change anything other than the cam (to mechanical lifter)?

I searched your build thread and couldn't find what trans you are using. I'm sure it's there somewhere but I'm a dork and missed it.

You can probably see where this is going. A copy of Todds drivetrain in a '70 RS Camaro.
Thanks,
Eric
