You may find that Lunati a little tame in a 455 compared to the Crane 296B but it will run fine.

Sorry, but I don’t consider a 4.56 rear geared 455 any where near a street car, and even back in 1978 it was not all that easy to turn up a set of 455 HO round port heads unless you already had such...

Yes, the hood latch support bar will need to be loosened and pushed out of the way. If the car has AC the condenser will need to be moved around but shouldn't have to be disconnected.

I bought an 1/2 stainless line for my first gen.

My one note would be to be prepared for nasty shipping costs. I think shipping was basically the same cost as the line in my case.

Just to comment, although Canton lists the pan as '6qt', that is the pan itself, so it should be 6+1 (for filter to fill). In some cases, another qt may be desired, so you can go 8 total, plus the...

You will be fine. The chain will stretch a slight bit. This is the street section and you are not after maximum HP, so if the chain retards 1 degree (when broken in) it is no big deal really.

3" Pypes x-pipe with Race Pro mufflers and 3" tips on my 74. It does tuck up very nicely into the body.

Steve, here's my take on the deal. The 455 is a HUGE engine. It is not a very efficient engine being undersquare and swinging pretty heavy parts. Piston speed is also pretty high in them.

420-430hp, 500 plus ft lbs torque. Peak HP around 5000-5200rpm's. With the 60919 cam, peak HP will be 5400-5600rpms, if you use high ratio rockers on it.

When we dyno'd my last 455 with unported...
