I enjoy your car and watching your progress racing. I had a 68 Sport Fury with a 383 330 hp that I did a lot of work on to race, reminds me of that car. If you are going 11s with that beast, I would forget about spending $600 on brakes and start looking for a Dana. Would be a shame to break the diff and all the other problems it can cause. Thanks for the posts!

Thread update! Weather was not crappy today, got the Firm Feel UCA's installed along with the Viking Warrior front shocks, so now the suspension is completely done! Just need to get it aligned.

Thanks to rickraw's Summit discount codes, I have a set of Trick Flow 270's on the way, ETA is sometime in June, and Wilwood rear discs to match my fronts have shown up already. I don't trust the 8 3/4 if I go any quicker and don't want to have to pull the trans every time I break it, so the plan is to order a Strange S60 this week. Was considering a 9" but the snout is about an inch shorter than an 8 3/4, so I'd need another new driveshaft, instead of my existing one getting shortened. At that point the Dana is cheaper. Planning on 35 spline axles, 4.10's instead of my current 4.30's, a truetrac, and about 1/2" narrower, so hopefully between the rear being narrower and the discs, the wheels will be easy to get on and off the car again.

I'm debating if I'm going to bolt the heads right to this shortblock. It runs great right now, doesn't have any blowby, and everything works together well. My concern is with better heads it's going to want to rev to the moon, and it still has stock weight TRW 2355's in it so I'm worried the LY rods are going to yeet themselves if I rev it much past 6500.

Option 1 is use the 270's on the 446 shortblock and run that for a couple years until my wallet recovers. I need to buy new rockers anyway, could pick up some 1.6 instead of 1.5 Harland Sharps to get the lift up to 0.630-ish, and leave everything else the same (850 DP Holley, TM7 intake, MP cam, 1 3/4" headers), and try to keep the engine speed below 6500 to reduce stress on the rods. Guessing it would pick up 4-ish tenths from the head/rocker swap, and then I could jet the nitrous up a little further which should get me solidly into the 10's.

Option 2 is to leave it as is this year, then over the winter pull it and put a lightweight 512 stroker rotating assembly in it, with main studs, new caps, fresh machinework, etc. It would also get the heads, a roller cam, MW sized intake, and I'd upgrade the headers to the 1 7/8" TTI's. It's only money, right? Lol

Thoughts?

Thanks,
Nick

GTX Matt- thanks for the heads up on the intake. I was hoping to keep my 4150 based carb and nitrous plate kit but if there is a ton of performance to be had by switching it I'd consider it! After reading Andy's articles on his 470, comparing the 240 to 270, the 270's seemed like a no brainer. Engine Masters did the same test, the 270's were better everywhere.

I think the 0.590 cam has 0.393 lobe lift, which should be 0.628 before lash with a 1.6 rocker. I might be doing the math wrong though?

493 John- I like the bench seat but I like the idea of getting weight out of it that way. I need to start looking at what can be cut out in terms of brackets and stuff.... especially for the backseat. Nobody sits in it!

a 7/16 wrench can make a LOT of power on a nitrous deal.......
