Agree, sorry to the OP, I didn’t mean to hijack. I agree with others sentiments about calling cam makers and getting their direct input. And I also agree that it’s a mistake to over cam a heavier truck- I saw it happen in a parking lot at Costco. This poor square was beautiful, but it sounded like a truck-pull truck from the 80s it was so radical and the guy looked miserable just navigating through the traffic there. It must’ve loaded up and gotten too much fuel because it died and he couldn’t get it started and people had to push him into a parking spot. But it could’ve been very poorly tuned as well. Either way, it was lifted, completely redone with big tires, and it sounded like it belonged on a drag strip.You won't get flamed from me on that comment. I completely agree. I still believe the Q-jet is the best carb for these engine in our trucks, but yea, the Edlebrock is second to none in terms of ease in custom tuning, or even ease of initial setup. For me with my stock 305 I'd love to have the Q-jet, but the PO installed an Edelbrock, and all the bracketry that was for the 700R4 with the Q-jet is gone. All I had to do the edelbrock was change the metering rods to get it where it needed to be. So $10 and 10 minutes of time. And that is why I'm still running the PO installed edelbrock, because it works fine. Now in the 5 years and nearly 80K I've put on the truck I have had to replace the choke coil twice and freeup the fast idle cam a few times. Which isn't bad, but if I compare that to the Q-jet on my 77 Cadillac, which if it's ever been rebuild it was before I bought it which was 15 years ago or so and it didn't look new then.
Sorry to the OP I did not mean to derail the thread.
LOL, I literally just pissed myself. My apologies to the OP. I'll stop now.You must be registered for see images attach
It’s all good I got my questions answered and everyone is having a good time. Doesn’t bother me one bit, some times going off topic turns into the best threads.LOL, I literally just pissed myself. My apologies to the OP. I'll stop now.
Check this guy out at Myvintageiron7512 on YouTube. He has some good stuff.So does anyone have a source for a place that explains how to chose a cam and whatever needs to be changed with it, possibly in crayon? Got a good ways to go before I’m at the stage of doing motor work on my grandfather’s truck. But I am thinking about swapping cams eventually. Always been told that they put a mild cam for pulling in the 50 year old 454 but have no idea of its specs. As much as I would love to put one in there that would sound like Vinnie Paul Abbot banging it out on the double bass. Probably need to go back with something mild but maybe with a little more spice. Figure by the time I get to that point I’ll have done enough research/learning to make a good choice.
You can overthink anything. Unless you are anal and OCD and building a competitive racing truck... you can go into any decent auto parts store or online source and buy a generic "RV" cam that will get you more torque and better fuel mileage. They are good for trucks you want to drive on the road. And you don't need to know the specific particulars of height/duration/whatever as though it will really make some kind of difference.So does anyone have a source for a place that explains how to chose a cam and whatever needs to be changed with it, possibly in crayon?
