Looking good Rick! It's getting close! Kind of weird seeing my old Miniram on your engine. It did support over 500rwhp N/A though.

Edit: Did you get the new ZF6 installed. The last pic's look like there's a 6 speed shifter.

Looks like the 4+3 still. I'm kind of curious how long the old 4+3 will hold up to those power levels...

Thanks. The motor will be fired up, and tuned this summer so I can drive it again. I have had so many ppl interested in what power this mill will make, and not to mention the driveability which is very important to me.

Obviously I didnt go out for all out hp, so it will be interesting to see how much power the small AFR ports make.

If I can hold with a C6 Z06 I will be happy.

Yes still the 4+3. I want to get this thing running first before I do the ZF6. First things first.....

Mine has only been around 2 yrs. Not cheap when you build a quality motor.

I think most dreamers dont appreciate what truly is involved in a commitment like this! Most people would have broken out in cold sweat dropping the kind of bucks involved here.

Don't get me wrong, I'm a dreamer, but I'm taking calculated steps in achieving my goals (defintely a test of patience). The hard part is keeping your eye on the prize.

Certainly is alot of bucks involved. I was lucky to have Jim in my corner in regards to cutting a few costs, or I might of not of been able to build the 421. If it wasn't a 421, it would be been a 383.

I am hoping we can turn it over July 1st, and I can hear the idle of the 236/242 with all those cubes.
