Hows the balance? internal? external? drastic change in piston weight?

Perhaps the low/reverse apply servo is sticking a bit and hits hard when it breaks free under higher fluide pressure in reverse?

How tight did you run them?

Its all b.s. . They claimed the pistons were delivered directly to a resident,which they were not. I complained and they responded claiming they were delivered to the wrong address and that they would investigate and give me a refund immediatly.They are clearly lying to you,me,and probably...

I checked the tracking no. they gave and they have supposedly been shipped via ups. We will see what happens as they say expected delivery is 3/15. Better not get charged $300+ !!!

Pretty sure you want .004 press fit w iron heads. check out you tube to be sure. seat pockets must be cut using finished valveguide as center to properly locate the new seat. good luck.

Thanks for giving the heads-up about the piston deal.

I happen to have 2 360s to build up,so they will get used in the not too distant future. assuming they actually show up,that is.

No offense,but i strongly recommend that you do a lot of homework before you proceed any further. Good luck.

Well, i got a shipping confirmation today. Im told the total was $107 and change. Havent looked on Amazon to see if anything changed since. No doubt they were supposed to cost more. Sometimes you win and usually you lose.

Anyone able to actually purchase these?

Probably try some thicker gaskets with some good fuel and oil resistant sealer on both sides of everything to hopefully seal it up without machine work. Fiber gaskets should compress some to fill a slightly uneven gap.

Sorry to say that your cam is too big for your compression ratio. It has quite a bit of overlap period [where both valves are open] which is causing very low cylinder pressure. Thats why it has barely more low rpm torque than the 318 had. The 516 heads are the way to go for you as you need every...

IMO....the most important thing is using a cam which has a power band or usable power range that matches the rpm range where your engine is going to operate. The next thing is having enough valve lift to use the flow capability of your cylinder heads to achieve the strongest performance, while...

if using 440 pistons on a 413 crank.......weigh the pistons on a decent digital scale. the 440 pistons will likely be heavier. grind the difference off the pin end of the rods, making them all the same as the lightest one. now you are at factory 413 balance and better because all 8 piston-rod...

whats been done to those heads? flow numbers?

an educated guess is..... more clutch discs in the forward drum,a higher ratio front band apply lever, higher rpm shift points via different governor weights and/or spring. just use 4 clutches in front drum, 4.2 ratio lever [if you can find one] and possibly get gov weights from a hp trans...

offsetting the seal ends aprox 1/8 inch will virtually guarantee that the seal lips line up on the two halves. i would mill or file .005-.010 off the seal retainers mating surface [to the block] which will compress the seal a bit more. that has worked for me in the past when i had a leaker. good...

check for voltage at the coil with key in the run position and crank position. if non present...check to verify voltage on both sides of ballast resistor with key in run position. if present on only one side.....replace ballast resistor. if no voltage on either side.....check wiring and ignition...

you need very good heads, lots of compression, and at least a 6500 rpm capable cam/valvetrain to get 500 hp out of a 383 imo. also a very good single plane intake and a big carb. then you will need 4.10 gears and a 3500 stall for an automatic to make it work with 3600+ ibs. nos would quickly...
