sorry for the late reply....

the roller lifter issues are mainly noise related, many of the 1st gen comp rollers were noisy, the didnt break or malfunction, just ticked a lot.  the later current versions of comps lifters are much better.  there are other brands out there like lunati but i havent read many reviews on them.

i use a butler forged crank/rods stroker kit.  crank is 4.25" stroke & .060 bored 400 makes it a 467ci.  because of the 72cc heads i did have the ross pistons dished a little to get teh compression down to 10.75 & it runs fine on 91 octane pump gas thats in my area.  there is a 93 octane but its 10% ethanol & the engine runs better on 91 straight gas.  its mostly a street car with a very stiff PTFB suspension, but so far does a best time of 11.2 at 121+mph.

I have a 1979 Trans Am with an Olds 403. It has been rebuilt and has an edlebrock intake. It also has a quadrajet Carb. Want to see if their is an aftermarket Carb that will fit that will let my shaker hood stay functional. My engine has 430hp. Please advise.

430hp?  That's got to be one of the highest hp 403s in North America!

Exactly. Some are set up for super quick and easy adjustment like the Holley but not so much in the fine tuning. QJets are almost too much fine tuning, they can work on any number of engine sizes and outouts and adjusted for all, but more involved. It comes down to what you want or need to change carb for.

Well, you know what they say about opinions.  ::)

I've always had really good luck with Edelbrock flavors.  The airhorn design makes for less leaks and fairly worry free.  Folks yell about tuning them, but my 02 gauge says she's spot on right out of the box.  YMMV, but for what it's worth I thought the Holly was way to finicky for street use and wasn't impressed.

Restoration / Re: How to separate exhaust?
« Last post by 76Tranz on March 20, 2017, 05:05:12 PM »
If you are not going to keep any of the stock exhaust, use a sawz-all and cut it all off and throw it away. As for the manifold bolts, soak them liberally with carb cleaner and then go back and soak them in penetrating oil. You may repeat this process a few times over a couple of days and then try breaking the bolts loose. It's always worked for me.
