Thanks for the update Blake! My credit card is standing by for the green light on the headers.

There are 15 sub frames in production now, all are sold! we are trying to have the all shipped before SEMA.

Will the new headers be exclusive to the new frames or will they work with your previous 1st Gen subframe as well?

I do not know. I will try them once we get the production set here. there is no reason the shouldn't but we will see.

Do you guys have any pictures of the subframe complete with the motor installed,headers and engine accessories?

Just curious of the space around everything. I know you said it was a tight fit.

Blake, you guys try a first gen block mock up yet?

We have not, we have concentrated on the LS to start. once the rush is over an we are caught up we will be able to go down that road.

I know the second gen that Roger is building will be getting an LT1 (old style) but he will be building his own headers as I think it will be a turbo deal.
first and second gen headers are not compatible.

I think the SBC will fit just need the time to do it. a BBC WILL NOT FIT, it will sit too high

Thanks. One more question. What is measurement from floor to fender lip at optimum ride height?

DAMN YOU!!.
It has been a while since we had one fully mocked up. If I remember correctly the bottom of the rocker was as about 5" maybe 6.
We started to go down the road of making everything fit with out body mounts to get a really low ride height but is limited front end travel. It made the trans/engine to high in the body. In other words it was a PITA, so after some consideration we decided to raise the body using the standard .800 thick mounts it also helped tire to fender clearance. There are SOOOOO many clearance issues that had to be worked out. A first Gen is still tight on the tire to fender clearance because this thing has so much steering angle. 31-32 deg on the inside tire. That is 6-7 more than Ron puts into his track star front suspension.

Yup, yup. I only set my Track-Star Front suspensions to have 25* steering radius. The Speedtech has 31*+.

Designing the new Speedtech suspension was challenging, fun & rewarding. We had so many goals ... optimum roll center regardless of travel ... zero bumpsteer ... 100% Ackerman ... optimum camber & caster gain ... 7, 8 & 9* static camber ... up to 3" travel ... fit 315 front tires AND have over 30* steering ... and we hit them all.

Sweet !
