Nice set of toys! Did you build this engine for boost? I saw that they used dished pistons and was just wondering.

My god is that chevelle clean! Is that a 454? Aluminum or iron block?

As for your hawk, it's a real shame about that shoddy workmanship. Especially after you had them build it with quality parts. What's the condition of the crank?

If you don't mind me asking what's the specs on the cam? Maybe it's just me but aluminum rockers scare me.

Thank you!

Originally I wanted to boost it, but the motor ended up taking way too long and was alot more than I wanted to spend with a blower. Specs say its 10.4 with a 57 CC head, but since I have it apart I'm going to check everything to see really where its at.

The Chevelle has a 580 built by Pro Motion Racing Engines out of NJ and it uses a Dart Big M tall deck cast iron block. Made 850 hp on the dyno when it was first done.

As for the crank, it looks good. Some of the bearings have some scoring, but nothing major. I'll be replacing them anyways.

The cam is variation of the CC502 with 528/535 lift using 1.6 rockers and 218/224 @.050 on a 114 ls. It has to get through inspection so I had to go light on the cam.

Now that I see what everyone else is doing here I could have probably went alot further with it.

Always feel free to ask questions or point things out. I'm still a novice with these cars.

Made some more progress today.....almost have everything out of the engine compartment. Last things I have are the main harness, the hood release and throttle cable. I might remove some of the brake lines too.

Now sure how to pull the whole harness....think I might need to disconnect a few things under the dash to get it out.

I talked to the body shop too about the project and I'll firm things up with them this week. Hope it will get down next week and back in a week or two. They had thought it would be a pretty quick job.

Just need to figure out where I want to go with the motor

Minor progress.......ready to go to the paint shop.

Still deciding what to do on the motor. Picking up another project today doesn't help.



Project.....LOL

I've been down this road; it can be fun if you have a solid game plan and the time/resources you need to finish.

Good luck with your build man. I feel for you on having such a nice car down for so long. Head gasket on my 95 hawk started leaking coolant out the back of the block couple weeks ago so have it torn down to repair it and may install a larger cam and new spring kit while im at it. going to pull the engine the rest of the way out of the car though and verify the condition of the internals before i spend money where it is not necessary.

Looking good sir! That Chevelle is sick looking! I would have Pro-Motion re-build your LT1 motor.

Thanks for the comments guys! The car is coming along slowly, but money is a little tight right now.

It just came back from the paint shop yesterday and they did a real nice job.



I have to concentrate on this one more than the others as the wife has been asking to drive it

Things kind of stalled out at the moment due to time......plus the wife wanted a new car so we picked this up for her and I have been slowly getting it in shape!

Thanks Guys!

The wife wanted t-tops a six speed and a Trans Am with the big wing. I figured it was easier to buy a car for her and then I get to fool with something new too!

Nice, you guys own two great looking Firehawks now. I love watching the old car test videos on the Firehawks from the 90s. Those things were bad cars back in their day.
