Doesn't matter how many times you see one...
...when it's a fresh rebuild, it just looks great. And when you rebuilt it yourself, it looks even better. It doesn't matter that the shroud is ratty and the fan is dull. It's a fresh motor!!!
This motor has exhausted me (and Tim). This engine doesn't seem pleased about leaving the comfort of my garage. The final insult came last night when the pressure-side oil line to the MFI pump stripped the fitting in the pump. After spending hours finding the right Helicoil and nearly bringing Tim to tears when I took the drill and forming tap to the MFI pump, the final (???) hurdle has been overcome. Some pics of the finished product, finally off the stand (I know, it's pretty boring after looking at Charlie's motor...) ![]() ![]() ![]()

Like Wayne said!
I noticed the sport conversion on the muffler...among other things. I bet in the scheme of things it was no big deal but how was it? Tough to do? Nothing like the sight of fresh meat...I mean motor - ahahahaa

Looks great, Dave. What are the final details on this engine? It's a lot more than stock, right? And where's Tim's engine?

It has been exhausting. Litterally every single major component minus the alternator has given us some sort of fit. I'm just glad its over and ready to go in the car.
As for mine I finally found a good case and pistons and cylinders, so I'll be on the rebuild path shortly. (I hate having to locate 30 year old parts) It's kind of depressing after looking at all the trouble we've been through, now I've got to do it all over again.

Thank you.
The sport muffler was made out of a ratty dual-in/single-out I had lying around. The machine/race shop actually did it for me, so I don't know how hard it was. They charged me around 2 hours shop time, so it can't be too bad. Jim, you're right, this is not a "T" motor any more by any stretch of the imagination. After failing to find a set of 2.2E pistons to stick in this motor, I took a page from Tyson's book and found some good 2.2T cylinders. These were machined with additional relief pocketing and the heads were decked 1mm. I bumped my shim up to .5mm, so my informal estimate of CR for this engine is now just over 9:1, a nice bump from 7.5:1. The cams are Crane 288, which appears to be very similar to a Solex cam with just a bit more lift and duration. The heads have been ported from 29mm to 34mm, with some nice smoothing and contouring done as well. The intake has been upgraded to "E" spec injection equipment, including throttle bodies, stacks, and pump. Exhaust has been upgraded with the factory-style sport muffler. Total costs to build this motor have been around $5k. There are a lot of nickel and dime costs included in this number. For instance, all those nice new hoses you see running around the MFI were around $100. That includes the new "snoot" from the warmup body to the airbox, which is around $40. I elected not to spend time and money on cosmetic stuff like refinishing the shroud or powdercoating parts - this engine and car are intended to be, after all, a driver. I'm going to be doing plenty of cosmetic work on the hotrod motor that's waiting in the wings.

Dave,
Awesome man.... That sense of accomplishment will feel even better (and somewhat relieving) once you hear it growl for the first time and put the first few miles on it ![]()

I can't wait to see it in the back of the engine bay. I bet it will run great!
