EFI drives the cost of the build up but, allows for greater tuning parameters on both fuel and timing. The other thing to look out for is valvetrain parts if you really want to spin it that high of an RPM.

I remember my old 340 Duster had either Cyclone or Headman headers on it and all the divers side tubes slip fit into the collector to allow installation.....exhaust leak city but, I was in high school and thought it was cool. Looks like a talented guy doing the header fabrication....NICE WORK!

On a Boss 302 on a street limited strip use type motor it's a blessing!!!

Fail! on a Boss 302 a 347 "stroker kit" is a blessing

That Offy manifold isn't a great piece but, brings up much conversation.

What are valve/reatiner weights......are you planning on using the India sourced junk AFR installs in their heads? I use Isky Gold Stripe springs myself.

Buy a 2006 or later....go with a 6.0 iron block if you can find one....about all of them have the equivalent of the 2002 Z06 head a decent part. The connecting rods in the 2006 and later motors are much better than earlier stuff. I wouldn't plan on extended 7000RPM operation, one of the reasons your...

This is a true story......my buddy who builds USAC Midget motors was building a Cosworth years ago......he had blow-by on a fresh rebuild was trying everything to cure it......the owner of the motor had supplied a set of Total Seal gapless rings....they weren't seating. It was a long 3 day holiday w...

Either AFR 180cc heads or Edelbrock Etec 170 runner heads for a little 302. I have the Z/28 302 from my old autocross Camaro sitting in the corner of my garage, it had 11.5:1 TRW slugs and a Crower 00350 cam in it (specs here: http://www.crower.com/camshafts/chevy-262-400-compu-pro-solid-small-base-...

Surging in an A series Mopar motor?....now your bringing me back memories of my wasted youth at Fremont Drag strip with my 340 Duster......that motor loved to eat valve springs and rocker arms until I put some 273 cast iron adjustable rockers on it. High speed surging could also be weak intake sprin...

The purpose of swapping out the heads was not for the sake of performance, but rather reliability since the GM heads have earned a bad reputation for snapping valves. Just how do the GM heads snap valves? How do LS7s "snap valves"? Well, you farm out the machine work of the cylinder heads...

Brad Penn is my preferred oil for vintage flat tappet motors.

As some have said, that intake was made for NHRA Super Stock motors, it was better than a factory intake but, distribution bugs need to be worked out of it from its production castings. I ran one of those back in the 70's, they were a pricey piece back then and I don't think many were sold.

Competition Products sold a lot of Canfield heads over the years as did Holley in their "System Max" line of top end bolt-on kits. Good Luck with the search.

hey carl, is the idler coated on the 55a, if not how do you know its steel We sent a set of PM gears back to Melling out of a 10553 pump (std volume M select series pump.) The steel gears that I recieved had a black coating on the idler gear. The Melling tech said they were having problems with the...
