Chad,
They look really neat,fitment good?
I can't remember if you dynoed engine with 4 into 1 or tri-y or both.
Great to see you chipping away on the malibu

I trial fitted them a couple times, changed some things, tweaked etc...before having them coated. I had a tube pretty much up against the column, I was debating on massaging that or moving it some, but I decided not to, I felt like the back of the engine was still up a little high and need to come down a few degrees when tranny is in so I left it...figuring that would resolve itself. I also ordered a slightly shorter set of engine mounts for when I did the final install...figuring it would help also

Well the shorter mounts fixed all the problems on the driver side up against the column and steering shaft etc, but I now have a tube just touching the frame on the opposite side now. So Ill have to put some clearance in it. Just sucks, now that everything is coated. I tried. With all the various angles of tubes and frame etc...its hard to predict what lowering the engine a 1/2 inch will do.

Overall they fit good now. Looks like I can even run mechanical clutch linkage if I want to. They did not fit the ports of the cylinder head well at all. That took more time than I envisioned to get decent. I mostly ran 4-2-1 on it on the dyno, but they didn't fit the ports great either and were not mine to go grinding on....I feel like these are probably as good now as anything I ran on it on the dyno, but I'll never really know.

Nice job!

Nice job!

Thanks. They could have been nicer as far as the Tig welds go. A friend did all that, and he was a little rusty. It's something he once did daily, but only occasionally now. So you can tell which header he did the collectors on first . But I'm pretty happy with them overall.

First of all this turned into a thread of epic goodness.....I spent a good 3 hours reading through it and taking it all in.

CGT and randy331, thanks and congradulations on your work here, great results that did not come easy!

2 questions.....what did you end up using for a valvespring package at the end for the compcam,
And what lobes did that compcam get ground from?

My apoligy if the info is in here and I missed it.

I think you will have a very badass car to drive around and enjoy with this engine and the way you are setting the car up.

Thx again for sharing this build with us.

The Comp cam was 236-247 109...xe intake huc exhaust off the top of my head.

The Manley spring was 221436-16...also off memory.

The Bullet cam was reinstalled afterwards, I felt it a better decision for the car overall.

[RevTheory]

You didn't drop $1,200 bucks on fancy-shmancy lifters to keep your Bullet lobes happy either, right?

[CGT]

It has the base Morel retrofit hydraulic roller lifter in it. I chose the Bullet cam because it has the ability to stay stable, at least more so than the Comp lobes past peak. I thought that would be more important in a semi-powerful street car with a manual trans, than the average torque gain from the Comp cam, which got into valvetrain trouble very abruptly. That xe intake lobe is very aggressive, especially for a relatively heavy valvetrain.

Once running if I have any trouble at all with shifts that accidentally happen after 7000, I will most likely change the current lifters out for some solid rollers. But I think I should be in the clear until 7500 with the Bullet cam. Hard to say if acceleration rates etc in the car vs the dyno will change any of that.
