427/425 stocker engine

Jesse Knapp · 04-12-2008, 12:21 AM

A few follow up questions. Does anyone know the superseded intake part number? I've gone through this before armed with only casting numbers for smallblock stuff. Dealership wanted a part number. I have an old GM performance parts book (1998) and this replacement piece is not listed. According to that book the 291 heads were still offered back then. Also, can Mr. Holroyd supply a carb. or do I find one and send it to him?Anyone have his phone number? Unrelated to this thread but curiosity on my part begs the question.....has anyone ever seen a set of 041 heads without the boltholes in them? I have a few sets of 041 heads and one set is blank. All my books show this head to have the three bolt holes. Date codes are June 10 and 17 of 68. I assume they were for the 69 yr. 350/300 engine. Thanks in advance. Jesse

Intake part # is the same as casting #, 19131359. Clark Holroyds # is 909-591-4320. Good guy to deal with. Good luck.

Thank you Joe Martens.

Jesse, there is a Holroyd 780 for sale in the parts classified section of this forum.

Thanks Jeff,,for the reply regarding the rocker arms and studs. That does sound like a good way to go, especially from a strength standpoint. I assume these are all in the GM Performance Parts catalog. I've got a friend with a 69 Camaro thinking about putting a 375/396 combo together after this season. We're in the parts gathering mode right now. Good luck on your season too................... Danny Durham

Thanks again, Joe. I thought it might be quite hard to piece together that engine. With help from racers on this website maybe not too bad. Originally I was going to do the 350-300hp engine for F/SA.since I have all that stuff and am more familiar with that. Ever since Bobby De Armond hit that 9 sec.run at Mission (I have that video and watch it quite often) I've been impressed with A/SA. and also his car of course. I'm leaning toward the 427, knowing it'll cost more, but if it doesn't work out I'll do a smallblock. Gonna check out that Holroyd carb. Again, thanks Joe. Jesse

Jesse you old dog,

Just couldn't stay away, could you? Yes, the early 041 heads were without bolt bosses. I've had several sets here. If I remember correctly, they all had 1967 date codes.

Boy, you're lookin' to jump right into the thick of things with an A/SA. It'll take a lot of dry-wall to keep that thing going. Just kidding! Glad you're thinking of a comeback.
