Dear Welder Series…
Hello I’m a returning customer. I have 50 Plymouth coupe that has a 600hp supercharged motor in it. I’m wanting to know which triangulated kit would be ideal (small or big bushing). It is a street rod but occasionally run at nostalgia drags.

And the other bit of advice or confirming what you said about 120 v welders. My Lincoln 140 hd 120v welder shouldn’t be used to do the final welding?
Thanks for the info
Thomas

Dear Thomas…
Thomas, I’d use the big bushing rear kit. We never had any problems with the small bushing kit but the large bushing kit is stronger and the same price. With 600 HP I’d add some support to the lower bar frame bracket.

I’d only use the 110V welder to tack parts in place for final welding by a heavier machine.

Thanks for using Welder Series parts.
