I've got a fairly rapid single seat race car; it actually cost me less than building a full on race engine for the 1200 and so the 1200 is actually my fun to flog car now.

First you can see a quick clip of the car running through turn 1 here.

https://www.facebook.com/83GusGus/videos/404529174435531

Currently I'm running the A12GX motor in the car has I've not got the A15 put back together. Most of that is down to my spending time on my single seater but I'll get the A15 done.

The A12GX has a ported head and the flat slide carbs; everything else is standard GX motor. It's probably making somewhere between 76-80hp at the wheels.

Top speed at this track is just a shade over 92mph. Turn one in the video sees the car doing 70mph at the apex.

My run group only had 8 cars so I pretty much had the track to myself.

During the first session of the day I decided to push on cold tires; on lap two coming through a left right section I got the car on opposite lock, I kept the lock on as it coincided with the upcoming right hander. Instead of snapping into the right hander Scandinavian flick style, it popped up on two wheels. Nothing huge, the inside wheels where 18-24" off the ground at best, it put so much load on the outside tires that both the front and the rears washed out so the car came right back down again.

I've done this twice before at autocross back 25-30 years ago. Same thing, Scandinavian Flick and once the car whipped into the right hand turn (left drive car driver on the outside) it popped up in the air. Back then we lowered the motor and trans 2". The car is now has a 3" wider track width so I was a bit surprised that it did this.

On the upside the course workers said the lover watching me drive it and the sound of the motor. After all these years (37 ownership 33rd year on track) it's still a fun car to drive.

I will be following your thread closely; I still have an E15ET head that I picked up to do the E head on A block thing years back. I still toy with the idea of running a NA E15 or 16 in my car instead of the A15.

Was there anything special to get the 60 series gearbox to bolt up? I'd love to know the details.

Wow I didn't know Dave sold the car.

Are you going to do SCCA GTL or take it back to original and go vintage racing?

ARP Head Studs & Oil to Head

For my A15 I'm using ARP head studs this time. What I noticed right away is the stud for the oil hole is the same diameter as the others whereas with the standard head bolts that particular bolt is thinner.

So will this matter? There is still a gap that around the stud that oil would flow through but is that enough?

The other thing I could do is drill out the block to so the oil passage lines up with the hole that is in the GX head.

Thoughts?

Are you saying it is sticking gear?

I had a couple of A-series blocks that had been modified to accept the E15ET heads. There is a huge amount of work here. There is a picture somewhere on the site of how the timing belt was done. From memory the tensioner for the belt was attached where the A12 camshaft inserted into the block. It was a custom plug with a stud on it. In addition to that the blocks had various water galleries plugged and I seem to recall some of the push rod holes. These blocks were strictly for racing. I had my fabricator look at the project and we determined it would be easier to simple for an entire E-series engine.
