hq wagon efi 304

Postby seanlivingstone » Sat Dec 01, 2018 3:24 pm

hey guys just thought ill share a bit of a engine swap we have been doing the last week or so. the 253 in the hq was getting extremely knocky and tired so decided to hunt for a doner car with a 304, found a vs ute that had a 304 swapped into it so most of the loom was hacked up and fairly hammered so that was the first thing out and i rewired it while deleting un-needed sensors and wiring and also adding. dropped the motor and box out and sent the vs for scrap. the past few days we have removed the 253 and trimatic from the hq and dropped the 304 and 4l60e in and wired it all up. so far having a few problems with the memcal but should have it fired this weekend and will be shortening the tailshaft tommorow so we can drive it down to the exhaust shop. :thumbup:

Hope you guys all had a good Christmas and new years :) just thought ill give a bit of an update on the wagon, got all the little bugs ironed out and has been daily driven for most of the month with no issues so far (knock on wood :lol: ), just got a new manifold for it but not happy with how messy it looks so going to probably go aftermarket fuel rails and need to work out a thermostat housing that'll suit better without going straight up other than that going to get a wideband and start to learn how to tune. Cheers

Nice. Just paint the fuel rails black, that will fix them :-)

Yeah that's what I think we are going to do. And want to convert the front link hose to a soft hose

Anodize them, it’s very cheap and there are plenty of places in Vic that do it.
