I do have a slight amount of the dreaded roller lifter tic but not enough to justify trying to mess with how my builder set them up.

It might just need adjustment.

Congrats! I think the exhaust tips look very nice. Car sounds great, although I'm not totally surprised that it's on the loud side. You have a serious engine under the hood. Regardless how how loud it is from the outside, perhaps a bigger factor will be how loud it is from inside the car while driving. If you don't have excessive exhaust volume or drone inside the cabin when driving, that should make it more reasonable to live with. The neighbors can deal.

37 trouble free miles other than a small power steering leak I think I found

It sounds great. What RPM is idle at and what brand lifters? Also, what oil viscosity?

61 miles break down free. I do want to be proactive about one potential problem. After about 20 mins idling in 75-80 degree weather the temp gets up to around 200. I can potentially see this being a problem in SC when it gets to be 90 everyday. Tips and tricks now?

Your AC condenser will inhibit air flow at idle. And now is a good time to check if it overheats with AC on and the condenser being an additional heat source for the radiator.

Check the cooling section for tips and tricks. Vacuum advance and timing, minimum clearance on water pump divider plate, factory clutch fan, air burped out of system, make sure all baffles and factory components in place. If it cools down at speed then it points to an air flow problem…

David, I'm in NC and experience some of the same possible overheating issues in slow idling traffic..
I used the 19" Pontiac 7 blade Hayden heavy duty clutch fan, 160 fail safe thermostat, and I removed the ( reduced flow)6" underdrive aftermarket crank pulley and replaced it with the original ( high flow)8" crank pulley .Now 172- 183 slow traffic idling). Pontiac 470 10.4 compression, solid roller engine.

Idle is at 850 and the lifters are Lunati. Little noise but not much.

My Comp rollers quieted down a bunch when I went from 1/2 turn past zero lash to 1 turn past. Glad to see that you're getting some seat time! Mine has been down about two years now.

Love it, what a nice feeling that must be, finally get to this point. Nice !

Hwy, how much power is that 442 making? I have a hard time believing there is no power loss with 2.5". I picked up 2/10 with 3" headpipes and wish I went all 3". I'm also pretty sure I was told by Dynomax that the STs start losing power past 385hp.

Could do the math and estimate it, but honestly don't know exactly. More than 385hp, that's for sure. Bernard said similar builds were in the 575 range.

442 has the trumpet tips that go thru the bumper cutouts, to get everything to line up, 2.5" is pretty much the max. They do make a kit, but have heard it doesn't fit well, and the 3" trumpet tips look silly.

So, just like on the GTO, and the Lemans before, with the splitter tailpipes, you pretty much need to run 2.5" on those. I know the 461 made more than 550hp, and the 535 certainly makes more than 600hp.

On all those, loosing a little is acceptable for my needs. I know I can run 3" up to or even past the muffler, I may try that on the GTO, will see. 442 is my daughter's car, and she's fine with giving up a little.

Ok so I have two problems. 99 and a half miles exactly , my car developed a skip so I pulled some plugs and my brothers expert "by ear" tuning had fouled 3 spark plugs. I replaced all 8 and it started running like a champ again. I got out my copy of How To Tune And Modify Holley Carbs and followed the guidelines exactly using my vacuum gauge etc and now it runs like a top but there is some collateral damage...in my exhaust tips. My once beautiful chrome exhaust tips are BLACK on the inside. What can I use to clean them out because laquer thinner on a rag aint doing it and neither is a wheel brush. Second my exhaust man pulled the connector off my sending unit when he was doing my exhaust. The little boot and terminal that connect to the sending unit is what I mean. I went to reconnect it after the exhaust was put on and the connection was not tight. I put needle nose pliers on it and tightened up the terminal that goes around the spade and got what I felt was a good connection but now my once rock steady fuel gauge is bouncing all over the place when I drive. If I sit still it gives me an accurate reading but as soon as I move its all over the place and it wasnt like that till it got jerked off the spade. What should I do to remedy these problems?

Car came out great David.

Congratulations on a job very well done.

Thanks!!! Still got a long way to go with interior. It’s LOUD inside haha. I need sound deadener and carpet etc. I have all the interior pieces except carpet but it’s gonna be a while till I have the money to do it.

Looks and sounds great. For sound deadener you don't have to break the bank with high-priced name brand. Two boxes of this - total of $130 -will do your floor and probably enough for your doors. Then you can move on with carpet install.
