Hello all. I'm new to this page, I've been over on the hsv/monaro page for the past 2 years. Just sold up after 2 years of fettling and modifying the monaro, got the LS1 up to 486bhp with all the usual mods (heads, cam remap etc etc) and started looking into getting back into drag racing so started pricing up tubbing it, putting a Dana or ford 9" rear end in and swapping the LS1 for a big block. In the end it worked out so expensive to build what I wanted it was easier to buy something already done which brings me here. I bought a '72 Dodge Demon drag car in October last year and have been slowly working on it to turn it into a road car. So far I've done the obvious things like lights/indicators, a horn, fuel gauge and sender unit in the fuel cell in the boot and general legal stuff, but once I got it MOT'd and out on the road it was a pig to drive. It's got a 451 big block in it so no power steering as it doesn't fit with a big block in the engine bay. It's got a predictably lumpy cam as it was a drag car which made it all or nothing and the Holley carb was jetted/set up for racing so it wouldn't tick over and kept cutting out when I took my foot off the throttle (turns out the carb was knackered and leaking) so now I'm just about to fit a Fitech fuel injection system on it and a big alloy rad to keep things cool. I've got no idea of the power output but it ran an 11.2 without a transbrake and 100bhp of nitrous

Sorry, but you are wrong there. Power steering can be fitted to big block Demons. The big problem is that you probably have the wrong 'B' block fitted. With the correct one, its a simple bolt up job.

So is it a bored 440 or a stroked 383/400 ?
Shouldn't need a big alloy rad, normal rad should be ok , IF the block & rad are clear, if its been a drag car only used at the strip occasionally, the cooling system is possibly clogged up with rust (I've just been working on a Challenger that is clogged up, similar set up/use, I had to drill through the rust build up behind the drain plugs in the side of the block)

A 451 will probably be a 400 block with a 440 crank and rods in it.

Normally, in the UK, the crank is fitted the easy way which leads to a weak engine....

Interested in how you get on with the FiTech system. Should finish fitting mine this week on a 302ci SBF powered Willys.
