Edelbrock kit is designed for tq and hp so you will have a fast street car not just a large hp number. On the street its the car that grunts down low will move first.

But yes it you cna add a bigger cam and get more power. A little more shold be fine. Alot more might be a bit more of a trick.

A true 400 hp is something many ppl have never had. If you can hit that mark you will ba dancing a jig and changing your shorts. Making that power at 4500 rpm is also very nice.

If you go with the 383 high compression kit it will make the most power ut may knock if the cam is not big enough.

The only bad thing is Edelbrock only has 2 flat tappet kits and I think I would be more satisfied with byeing my own parts but then again the parts in the kits are probably what I would get anyway but wouldnt it be better to go with something like summit racings aluminum 200 cc heads instead of edelbrocks 180 cc or 185 cc heads.

Edelbrock 2022 Edelbrock Power Package Top End Kits

Edelbrock 2098 Edelbrock Power Package Top End Kits


Also TechInspector1 what would you say about getting a scat 383 rotating assembly thats already balanced and comes with everything including rings so I dont have to figure out what goes with what like the one below. http://www.summitracing.com/parts/sc...make/chevrolet

Scat 1-92000 Scat Series 9000 Cast Crank Street Performance Rotating Assemblies

This is the only 383 c.i. kit I could find through scat thats 2 peace seal but the compression ratio is kinda high but I guess I could go with a different fuel. Its not a daily driver engine anyway. but it would be nice to use pump gas.

Thank you all for all the input. I greatly appreciate it. Sorry for all the questions.
Summit Racing has this kit with the 2pc rear main seal and the dished pistons for 9.5 compression with 64cc heads.http://www.summitracing.com/parts/sc...make/chevrolet

ChevroletSS, since you asked about a Scat balanced rotating assembly......... Scat #1-90350BE has a Scat 9000 series Pro Comp lightweight crankshaft, Pro Comp 5.7" I-beam rods with 3/8" cap screws, 18cc D-deck pistons, plasma moly rings, main and rod bearings, flexplate, and balancer, all balanced from Scat.

$1086.95 at Summit Racing

$1035.99 at Jegs

$979.00 at Flatlander Racing


If you prefer to have your balancing done locally Scat #1-90350 is the same kit minus the balancer and flexplate, and is not balanced. $833.95 at Summit Racing

$833.99 at Jegs



The 18cc D-deck pistons (D-deck for a good quench) assembled with a .040" quench with 64cc chambered head (64cc gives you the biggest selection in available performance heads) gives a static compression ratio of 9.68:1. A Summit K1103 cam/lifter kit would give a dynamic CR of 8.56 on the KB calculator, this puts you dead on techinspector1's recommendations.

Thanks for the help guys, it was very helpful. One more thing. Just curious to how a 400 crank in a 355 makes it have 28 more c.i.. I thought cubic inches was the space that the engine had.

Hey also I have another block out of a early nintys chevy 1500. It is machined for a fuel pump and has provisins to be a roller. But the three hole are not threaded. I have a tap and die set. Anyone know if its fairly easy to thread these holes. I dont want to start trying and mess it up. Also anyone know where to get the plate that goes in the lifter valley.

The displacement of an engine is the measurement of the space displaced by the up/down movement of the piston in the bore, not the measurement of the actual amount of space in the engine. So a bigger bore makes more space. A longer stroke also makes more space. Think of it like a can, if you make the can bigger around (bigger bore) it will hold more. If you make the can taller (longer stroke) it will hold more.

Your early nineties block will be a 1 piece rear main seal block so it will need a different crankshaft than a 2 piece rear seal block. The 3 holes in the lifter valley for the lifter retainer "spider" can be easily done, your machine shop would have no problem with it if you're uncertain. You will also need the front of the block prepared for the cam retainer if you're going to use a roller cam. You can still use a flat tappet cam/lifters as the block is now.

ChevroletSS, the build I suggested would fall under your "torque monster" classification, it would still have very respectable horse power but wouldn't really fall into the "high HP" class. This will give you a 383 that will pull from a fast idle speed to over 5000 rpm (so it'll work well with stock torque converter and hiway gears, but even better with a higher stall and lower gears), it'll be reliable, and it'll do it on pump gas.

Hey guys Its been awhile since Ive posted on this post. Ive decided to spend around 1500 on heads. I want to up my HP goal from 400 to around 500. I know ill never know what HP numbers ill have with no dyno but I want something that is capable of producing that much. Is this realistically possible to do with heads around 1500 bucks??? Any suggestions. If I have to go up to 2000 bucks I will. It would be awsome to get over 500 HP. Just to update you all this is PROBABLY going in my 79 elcamino. Not sur yet. Will be carburated.

Brodix heads 210 cc intake runner 2.02 or larger valaves. You should be able to come close for 2 Gs 1500 will fall short and only get close woth good tune. Best to get the right stuff. Comp 294s is a good cam that has made around 500 hp for me in the past.

If you got 4000 you can look at some gpod used 18 degree heads and intake cam combo. And make well over 500 hp. But stock bottom end even with arp rod bolts will not hold up at all.

Wow makes it a little easier seeing dyno rsults. I like the SBC 195cc Street Competition Package. They make 692 Hp and 611 Tq and they cost just over 2000 for the pair. I think these would be a great fit for what I want on my build.

The 692/611 is made with a Weiand 6-71 blower. Naturally-aspirated, the heads make just over 500. I'd be interested in the 1034 or 1036 part numbers, depending on chamber volume you want to work with. Straight plugs will work way easier with header tubes and flange plates.
