    Nicks Garage 383 build

    I think headers would have achieved the magical 425 ft-lbs he was chasing. Or at least taken it within spittin distance. Too bad he dislikes headers so much.

    [WANTED] .040 or .060 Speed Pro/Sealed Power L2388 pistons

    I was thinking something between 1.91 and 1.93. Silvolite 1276 would fit the bill, and might not even require a re-balance with a light pin, but it's a cast piston. I could use a cast piston, but I wanted to see what else is out there. Don't want to use KB hypers due to their gigantic 8cc valve...

    [WANTED] .040 or .060 Speed Pro/Sealed Power L2388 pistons

    Hmmmm I'll have to give it some thought. I'm looking for 440 pistons to use in a stock stroke 400. The compression height on those would put them .040-0.050 above deck on my block. Might be a little too much.

    [WANTED] Direct Connection big block 400 11.5:1 pistons. P3690831 or P3690832

    Looking for a set of the old direct connection 400 dome pistons in .030 or .060 over.

    And about the same torque per cid as the “weaky” 383. And the same power. With probably the same casting # heads and similar compression.

    We’ll see on Monday if it’s actually sunken exhaust valves.

    360 vs 383

    Maybe they wanted a few extra cubes in an attempt to make up for the drop in compresion?

    360 vs 383

    I think the last year for the 383/335 was 1970. By 1971 Chrysler dropped it to an advertised 8.7:1 comp ratio, and was rated at 300 gross/250 net horsepower. Makes sense that a heavier car, with less gear and just 5 extra horsepower is the slower of the two. Converter stall also plays a role...

    360 vs 383

    If using a 904 is an option, in the mildly hopped up scenario I might say its a tie or down to personal preference. I'm not sure if the lighter transmission and reduction in drivetrain losses completely make up for 23 extra cubic inches, but the extra room in the engine compartment will sway...

    360 vs 383

    1. 383. Might be a bit heavier, but keeping everyhting else equal it still has an advantage. "Bigger" heads, slightly bigger cam, more compression and 23 extra cubes. Might be held back by the smaller carburetor vs a T-quad on a 360 but not by much. For scenario 2, 3 and 4 I would still choose...

    Video's (youtube etc..)

    I noticed the thing with the exhaust ports too. A 5.3 head gets better flow with a smaller valve than a magnum head. Heck, the LS3 heads have tiny 1.59 exhaust valves that can flow in the 190's @ .500 with that port. Thats still a smaller valve than the Magnum.

    Video's (youtube etc..)

    I’ve had this thought for a while. I think it’s the ports. I bet if you analyzed one of those ports you’d find it has good speed and port energy. Plus the combustion chamber is 40 years advanced vs our old iron heads. And they respond to cam swaps well because the factory cams are tiny! On non...

    Isky 264 Mega in a 400

    Yes. I can get 93 octane on any gas station where I live. I'll have to be careful with the timing curve, but I think it's doable. I just wish all these old iron heads had a quench pad like the small block chebys, i'd push the compression up a hair.

    Isky 264 Mega in a 400

    Yep, it's a 108 lsa cam. Awesome! I don't want a rowdy idle with crappy vacuum on this engine. I still had some doubts about idle quality since I wasn't able to find a video on youtube of that cam idling. Everyone seems to go for the 270 Mega or bigger, and by that point idle quality is...

    Isky 264 Mega in a 400

    Awesome! The LSA was one of the major factors in choosing it. I rarely see people using short, narrow LSA cams and I wanted to give it a shot. Would you happen to remember how was the idle quality on that Pontiac 400? And at what RPM did the cam come alive?

    Isky 264 Mega in a 400

    Hi everyone. Anyone here ever run an Isky 264 in a 383 or a 400? I have one I’m planning to use on my 400 build. I’m shooting for 9.5:1 compression on this engine, I’ll use a 727 with the factory 10.75” converter, and the car will have 3.21 gears out back. I’m pretty confident this cam will fit...

    OEM style valves - SBI vs Melling

    Understood. I actually did consider getting Mancini 2.08/1.74 valves but settled on replacement stuff since I’m not going crazy on my current build and want to keep budget creep in check.

    OEM style valves - SBI vs Melling

    So, if it were your build, you’d go for the Melling over the SBI valves?

    OEM style valves - SBI vs Melling

    Hello everyone. I have a Melling v0548 valve and an SBI 00548. I have noticed there are some differences between them. The SBI valve has a step on the underside of the valve head, and its finish is different than the Melling. (SBI on the left, Melling on the right in the first and second pics)...

    750 Brawler vs 650 AVS 2 at the track, right OOTB !

    Thinking about installing a hair bigger cam in that engine?

    750 Brawler vs 650 AVS 2 at the track, right OOTB !

    I never got to try the thick gasket. I switched the AVS2 out for an old school OEM AVS and the heat soak went away. I think it’s the bowl vent valve on the factory carb that makes a difference.

    750 Brawler vs 650 AVS 2 at the track, right OOTB !

    I was expecting both carbs to perform similarly. But I definitely didn’t expect the AVS2 getting the best MPH. And just about matching ET with the Brawler! Never thought they would be soooo close. And the AVS2 is 100cfm smaller. Wow! All edelbrock needs to do now is do something to address...

    Hydraulic lifters - are these good?

    Thanks for the input guys. I won’t be using them. Regarding re surfacing older lifters…… the set I pulled from the 400 all looked good, didn’t look like they failed or anything. I can post pictures later. My question is, would those be a candidate for re-surfacing? Is there something else to...
