I'm going to try and look at some cars when spring rolls around but I don't that I would fit in most used cars 50 inch chest and all shoulders most cars you see are built for small people for some reason???
jeff/21:
there isn't a big price differential between DOM mild steel and CM . either will work as stated CM frame the resale value is better and easier to sell but needs more experience is needed to weld but the big thing is alignment and how far out you want the motor, a Greek Coupler is the best but I used a trans yoke- U-joint diff yoke with no problems 406 sbc/ powerglide

We use chromoly at work on some buggy's and sand dragsters.ive always thought it's brittle expensive and hard to work and cracks seem to run compared to do?I have way more experience with mild steel we build bombproof rock buggy's with BBC engines and Rockwell's but they don't have the NHRA inspection and sfi specs like the dragsters.resale will not be an issue with what I build it will be a keeper the people here seem to know there stuff and I never have been the kind of person to find someone to answer my questions with the answers I want there is a lot of knowledge to be found here and I appreciate it

As Jeff noted, 4130 is not much more expensive than DOM and if you are finding it brittle, hard to work and prone to cracking you are doing something wrong.
