Another thing to consider is the fuel system. Would you also have to do high side work and low side? I had to do a dsx low side on mine because pressure was dropping. So wouldn't the bigger 454 need more fuel which drives up cost even more?

A naturally aspirated mild 454 would demand less fuel than a blown LT1. Remember, forced induction LT1s need to be tuned much richer than naturally aspirated LT1s. A mild 454 could probably get a away with a full LT4 fuel system.

I get that so thats what another 1500 added to the price. I'm thinking that people don't do the 454 because of the cost vs actual performance you get is not worth it vs the alternatives. There are probably some other factors just not enough people go through the trouble. Weapon x is the only place that I've found that even offers a 454 on their site everybody seems to stop at the 427. I'm sure with enough money any shop would build what you want like the ARS car but I don't even want to think about how much that would probably cost.

Having done 400 to 455 rotating assembly swaps in real Pontiacs, the extra stroke and cubes is very nice even in a mild or equalized cam. In this platform it’s a crazy premium tho as you mentioned it’s tempting to get the bigger cam to cash in. I’ve been there on a few occasions with a too routty of a cam and needed to go back in more than once. Shame it’s so big of a job on this car. 4th gens and Abodys would have the motor out on Friday and driving it to work Monday, doubtful on this one.

Yep too much money and I don't have the time or a lift big enough to do it myself. May not be on this platform for too much longer anyways as I stopped at my local Toyota dealership and was told they have a Supra coming to their lot thats not spoken for so this car might be getting a for sale sticker slapped across if I enjoy the test drive too much.

Those are fast as sh*t, if you are cool with the automatic, have at it. For rwd, i need an M6, slow as it may be, still always fun. If I had to have an auto drag car, it would be an RS3 with the works, 1000 hp awd fun on the straights.

I'm absolutely fine with an automatic never even driven a stick car. It would be my daily driver just like my Camaro is now so it wouldn't matter what I got it would be an automatic.

Because a larger engine with a mild cam will drive better and offer better reliability then a small engine with a large cam...large camshafts often require a lot of attention to detail in the valvetrain to offer decent longevity. Larger cams shift the power curve to the right, you have to make the low end up with compression. A lot of compression can require more octane in order to run optimal timing. It's all a balancing act really...stroker engines usually have a very flat power curve and make power everywhere which makes for a fun street car...similar to putting a PD supercharger on a stock displacement engine. I don't however recommend stroker engines with PD superchargers.

I totally agree with King, its just not necessary for a large displacement on any blower. Big cubes and NOS is what you see in Pro Mod and smaller cubes for Procharger or Turbo's and PD blowers. Obviously these are way different then what we do but same concept.

Curious as to why no pd blower on a stroker motor. Is it because all the torque generated from the motor already so traction becomes the issue or is there actual problems that pd blowers exhibit with the larger cubed motors?
