If you're on Fartbook you may have seen this, anyway I've been working on some "power bulges"

Cover up the sticky-out bits with glad wrap, spray foam it & sand to shape goes pretty quick Mate. Use polyester so it doesn't eat the foam.

This worked pretty well for using what was "at hand"....pretty tough too.

update.

Formerly the car had exhaust that ran down and the along the floor of the car joining behind the rear bulkhead and exiting in a single pipes the tip of the tail. The cooling system was total loss with a 60 litre (12 gallon) steel tank that when full weighed 100kg (220lbs).

The new Chev V6 is larger up top buy also has slightly different dimensions in other areas. Because our diff housing is fixed we only had a small amount of flexibility with the height of the drive line without undertaking significant earthworks. We decided to use engine mounts I stead of the engine plate to mount the motor. This meant that the motor sits higher and slightly further back than ideal. This means that the exhaust had to go straight back, there is no room for it to go down. Because the motor is longer the water tank would not fit. Because the tank has "floors" welded into it to cause the water to circulate it was not possible to spot shorten it. With this situation we elected to use a radiator and an electric water pump. Norm Harding's came to the party and made us a double core aluminum radiator with a large thermofan and also flicked us a Davies Craig ewp150 and a US a small block water pump delete kit......Because we have a radiator we now have heat isolation issues. The exhaust heads straight back along the mostne and exits through a 3/8 steel flange. It is the world's ugliest set of headers. This week we will use fibreglass to form some air ducts to take cool air under the radiator and avoid the exhaust allowing the fan to send heat out of the louvres along the back of the cowl.
When we built this car we built it around the original Holden V6, I'm hoping the compromises we've made in this refit don't rob too many HP in drag and lessen the gains we have made power wise.....

Yesterday I made a jig using a Hitachi sander polisher, a disc of particleboard and some string for a footswitch. I clamped the polisher. I screwed the moon discs to it and used coarse paper to freshen them up, getting rid of the oxidation and keeping the same spun look..... I welded up some cracks in the bodywork and some redundant holes too, I also spent a few hours making lethal steel splinters with a die grinder on the headers.Today it's bodywork, the new scoop and the nacelles for the heads....right now the list seems endless

We are NOT rebuilding . . . We are reloading.
