come up with casting numbers off everything.... both blocks.. both sets of heads.... intake... that will make getting you a proper answer easier... say... is that a roller cam??? conventional tappet cams cannot be swapped from engine to engine as they have been broken in to specific lifters and lifter bore angle differences... what.. in conventional cams. the egg shaped lobe is ground with a tiny angle across the face.. the lifters have a convex face... so when the cam rides on the lifter.. the contact patch is slightly off center on the bottom of the lifter.. this causes the lifter to spin slowly as the cam goes around... change the lifters into a different order... or cam and lifters into a different block.. the angles might be slightly different and cam failure usually follows soon afterwards.. if you are going rock climbing... you might want to think about a fuel injection system... so the float bowls won't be effected by angles... hint... one with massive angles in the future... might want to have a second fuel tank or accumulator.. so the fuel pressure does not drop if the fuel moves away from the in tank electric fuel pump are you also aware that there are a bunch of truck magazines on this site also???? click the source internet media icon at the bottom of the page... and then the Our sites tab...

3795896 283/307/327 58-72 1.72/1.50 60cc This is what my reference material shows for a set of heads that could be the number you have. There are no head casting numbers beginning with 8. I have to agree with Bob, the motor sounds like the original and would have a 2-piece rear main seal. Any small block prior to 1987 will have a 2-piece rear main seal.

Ok sorry its taken me so long to respond the last couple days have been crazy and after having to pay for a small medical procedure out of pocket im now changing the direction of the build and am going to keep the stock iron heads and deck them to bump up the compression a little and port and polish them. The block number is 10066036 which when you run it turns out this is a Goodwrench or "targetmaster" crate engine so it is a truly new motor sadly it was made in mexico and not the us lol. The heads are casting number 10066036 which are 76cc heads. After reading the mouse motor build they are 76cc heads with 1.94 1.50 valves which they say if you deck them it takes them down to 73cc and bumps up the compression a little to a whopping 8.4 to 1 and a port job and bowl blend does wonders for them. The Holley intake 300-38 i have turns out after doing research is the same as the stock intake so now im shopping for an intake. The cam that i have thats been sitting on a shelf for a couple years is magically damaged so now im also shopping for a cam and looking at the comp cams 268h. So my questions now are should I keep the stock valves in the head and change to 1.6 rockers to save the money or should i upgrade to 2.02/1.60 valves when i deck the heads and port and polish them? Also what intake do you like? Ive always ran just edelbrock performers but i know some of the other intakes have different advantages and i do want to make the most out of this since im stuck buying the parts. What are your opinions on the comp cams 268h or should i run a different cam. Im not worried about fuel economy as this is just a recreational car/toy I have 2 different carbs in front of me that i can use. A Edelbrock 1400 600cfm electric choke and a Holley 3310-4 750 cfm any opinions?

What engine is it? Size? Is this a 383 as the thread title suggests? I have seen threads titled one thing and questions generated about another. Maybe some other specs like 2 or 4 bolt block, bore, stroke, deck height since the heads are off, shape of tthe piston tops, i.e.; flat w/2 valve reliefs, flat w/4 valve reliefs, dished, domed, cc of valve reliefs, cc of dome, what heads you got with it, valve sizes in the heads you got with it, what cam you got with it, specs on the cam you got with it, what vehicle you plan on putting this motor in, how you plan on using the vehicle the motor goes in, i.e.; street only, mostly street with some racing, mostly racing with some street time, racing only.

I have seen weak and/or broken valve springs cause low or dead cylinders. Luckily for the customer the keepers and retainer stayed in place. The valve spring was just slighty shorter in appearance while still on the motor, it barely caught my attention but was causing run problems. just some input, food for thought

Performance chips work in conjunction with other mods such as better flowing exhaust systems and better flowing intake systems, not just a different air filter or different muffler.

I am planning on replacing all fuel lines on my 81 Z28. I am doing this because I think my Holley is leaning out because of not enough fuel being delivered to the carb. Question is if I plug the fuel return line at the fuel tank will this effect fuel delivery? I do plan on replacing the pickup inside of the tank also so everything will be new. Is there any options for a single line sending unit? I did find one but it was the wrong year and wrong engine size.The pump I have on does not have a return line fitting. Nothing about this engine is stock either.Thanks!

I use a piece of 8 mm hollow aluminum tubing.It's been slightly pinched closed at one end so I can turn the "D" heads of the mixture screws.It's pretty redneck but it works,and was a lot cheaper than buying special tools that will only be used once.I also use the same thing to adjust my metering rod plunger.

Advice from others is fine but all to often one will get a different answer from every person asked. performance chip...Yes high flow exhaust...Yes high flow/erformance air filter...Yes Everyone knows to increase air flow INTO the engine but what many seem to forget is that the air flow OUT of the engine needs to match the flow in for performance to be optimized.
