Re: Big Block mounts
I used these new frame mounting brackets and engine mounts on mine and it worked out nice.
https://www.performanceonline.com/19...-Brackets-V-8/ https://www.performanceonline.com/Ch...urethane-Pair/ I don't have a pic of the brackets installed without the motor. I moved the brackets about 1.25" back (drilled all new holes and filled in the old ones) so my electric fan setup had enough clearance up front. I did a 700R4 swap so I wasn't trying to reuse existing mounting for the transmission xmember I just let the xmember dictate where it needed to go. Not sure if this was the info you're looking for. My C10 had a SBC originally.
