1. 70 Challenger, 3.55 gears, limited slip differential, 4 speed HD Keisler automatic transmission, 512 cu inch stroker motor, fuel injection, 1 3/4 TTI headers, TF 240 aluminum heads, some fiberglass and lots of aluminum parts Still some parts to get. Will choose converter after buying a camshaft.

2. Usage, street racing, street driving, going to the drag strip every couple of months, some autocross events.

3. It will be driven on the street, 2 maybe 3 times a week.

I have looked at several cams what do you think.

Lunati 20230712 231-239 @50 535/550 lift 110 lobe separation

What do you think? Any questions or sugestions? There are A LOT of Super Smart people here on Moparts and I value your opinions.


Thanks,

AL

I would probably use the Lunati installed 4 to 6 degrees advance on the intake lobes and I would put a set of two inch headers on that motor also so it can breath and not be choked down in the upper, above 4500 RPM , range twocents
I'm thinking that cam and headers will probably make peak torque between 4000 up to 5000 RPM and peak HP between 5500 to 6300 RPM so shifting it at or around 6300 to 6600 RPM should set you back in the seat hard enough to make you either grin or cringe devil whistling
the 1 3/4 inch are two small, make the rest of the exhaust system 3.0 or larger also up
