    Things you should never do to a 71 Plymouth

    I'm guessing that its an auto with a pistol-grip? Lovely interior and very modern looking! The outside went a bit astray and why fit a 392 hemi in a modern Mopar? I suppose it looked naff so they covered it up with err covers..

    71 Roadrunner Chassis Repair

    Thats right Nacho. I bought a real nice 71 Charger Superbee in 'BURNT ORANGE' a while back and someone with 'rose coloured' glasses had started doing major structural work to it. New full floorpans and replaced the rockers, but the lower firewall area and A-posts were like 'swiss cheese'! Poor...

    71 Roadrunner Chassis Repair

    That’s perfect Nacho! Unpick the firewall and rocker pieces then weld the whole lot in. This will be the answer to all the alignment issues and a proper job too!:luvplace:

    71 Roadrunner Chassis Repair

    Hi Otto, with severe rust issues the frames/body could be out of alignment. The only way to change framerails ‘properly’ is on a factory jig! They have pegs/supports to hold the rails in place prior to welding. It’s like staring a jigsaw from the middle outwards... Difficult. Most sensible folks...

    71 Roadrunner Chassis Repair

    I have been a crash repair guy in the motor trade and ‘butt welding’ frame rails, especially front ones is highly frowned upon indeed! This would not pass tech inspection in the UK and is dangerous in a big crash! Fine for a show queen, but I would not want to ride in this Charger, ‘just in...

    Son of a Gun!

    Hi qk, they are called ‘Weslake heads’ and were cast by mother Mopar back in the late 60’s. Supposedly to replace Hemi heads on the banned 426 NASCAR engines for 1970. Big block W2’s or as I call them W1’s lol. Only two pairs ever made, this set of stock open chamber and another set at the ex...

    Son of a Gun!

    Great read indeed! Nice to see stuff like this still being done. I had my 440 crank 'turned down' for my 4oo block but didn't know about the throw issue? Will be using 440 rods with o.990 pins and 440 source stroker pistons. Gonna go with some 452 heads as they is hard as iron lol. My Moparmate...

    71 Roadrunner Chassis Repair

    WoW Otto thats very rusty indeed! I have spent twenty years de-rusting my 71 GTX and its NOT easy! I started with TWO good front rails and one very bad rear rail. A Unibody is very strong once the metal is all good, but once you start stripping back it will have to be well supported! If you...
