The Official Hot Rod Thread - Part 4: Burnouts for Distance

I agree most modern engines seem to benefit more from higher octane/better quality fuel.

Yep. Modern engines generally have higher compression.

For example, the new stock Mustang GT 5.0 is 12.0:1

Rio is also. even the turbo 1.6 in the new car is 10.5

Any local machine shops anyone would recommend for head and block work on a small block Chevy? I have a 355 that just got broke in and a wrist pin moved over into the cylinder bore and destroyed the block because it didn’t have enough press. So I am also looking for another 350 if anyone knows of any standard bore motors fore sale.

I had Quinlinn build my 351 last year. To be fair, I haven't finished assembling it with a cam/heads so I can't say much else. I got my new/used crankshaft and new rod/main bearings for my 302 from him. I did the assembly on that one.
My father-in-law is the one who recommended Quinlinn. I hope I don't need engine work done for awhile, but I'll take it back to him if I do.

Hey, have you guys heard of King Bearings? I have an upcoming interview with them next week and the person I talked to today said they have a good name in the performance markets.

Coming from TRW/Federal Mogul, I had my opinion on who I thought made good bearings and I have never heard of King before.

Are they all that and more?

Something must have changed in engine design. Many modern engines are 10 or more to one and can run fine on 87 octane unleaded gas. In the 70's we had to run premium gas, often searching high and low for leaded. And they would still spark knock. Moroso used to sell lead additive and octaine booster if all we could get was Amoco unleaded premium

High quality electronic fuel injection and computer controlled ignition timing are the biggest advancements in the past 15-20ish years.

It’s a total package though. Heads are way better. Combustion chambers are better. Tolerances at tighter. Variable cam timing. Etc.

I have heard them mentioned by a couple of guys that are big into imports. Don't know anything about them though.

Aluminum heads are way more common now, along with what CP mentioned.

I pulled the intercooler out of the truck the other night. Has a decent amount of oil in it.

Any recommendations where I can take it to be cleaned? Can someone like Quinlinn hot tank it?
