Just a quick outline of what i am doing this week to my wagon. I am going to run it on the eighth on Sunday at The Six banger Nats. Car is stock apart from extractors and exhaust, i am on my 3rd etractor gasket so had to have a look at that before the weekend. I am wanting to tune her up a bit without breaking the bank. I had a collector welded on today and a 2.5 inch side pipe that exits under the drivers side door, my exhaust was Hi-Tech Headers, 2.25 into a Hooker Aeroflow, then 2” to the rear, i hacked off the 2” rather crudely to dump it before the diff. The new exhaust mods now have a 2.25 from extractors to the collector, it was 2” for some reason then 2.25 so its now the same, had a new turndown fitted with the muffler slightly angled so it dumps at the tyre shock area. Painted it all satin black. Unbolted the exhaust at the collector and took the extractors off, pretty bad to find a 4mm gap front to back and a bit of a bow in these extractors, they are mass produced, the workmanship is nice just not checked probably. I notice the middle ports had quite a bit of interference where the pipes meet the flange internally, my friend is fixing the extractors and porting out the middle ports to fix it up then face it all up.
When i race it on Sunday going to do so with the pipe up, air cleaner on and my big 15”wheels and tyres. Get a few runs, then unbolt the exhaust, bolt the side pipe on, remove the air cleaner and put my 14’ steelies on with small tryres, this should get it off the line quicker and i will be able to see what this adds up to, the day of racing is six cylinder only so after a few runs, get a dial in and try and go some rounds.
Going to change the oil (anyone recommend a grade?), oil filter and do something with the plugs, also the timing hasn’t been done since i brought it 13 months ago. Dizzy is points but its all newish, jusdging by the amount of carbon/soot etc in the exhaust ports it must be running a bit rich, i haven’t touched the car. Car has always ran very well. Any tips on the tune up?
