Building a 355

Okay so I'm very new at this and have a basic understanding of engine building. I have a 350 block bored at .030. I'm not trying to race it but I do want it quick light to light. I don't know what to do about heads, intake, carb cfm and cam. Any advice would be nice and very appreciated. I would like to get 400+ hp and tq for a reasonable price

you can hit 400hp/400 tq with a bone stock 350 short block. If cost is really a concern I'd reuse the stock crank and rods and find some flat top pistons close to the weight of pistons last on it so you don't need to rebalance.

Top it off with some import heads, a good dual plane intake, a solid flat tappet cam, headers, and a well tuned carb and HEI ignition and you'll make a LOT more than your target goals.

If you can afford to step up on the heads I'd look at the Jeg's or Summit heads.

The heads will eat up the largest part of your budget, but they're also VERY important.

If you are careful in part selection you can have 400-500hp and in the 400-450 ftlb range for about $2500.

The block I got came with pistons and rods for it already that had already been machined, and it came with heads that are 76cc heads with 194 int and 150 exhaust and from what I've read and been told those are too big unless I'm running FI which I'm definitely not so what should I look for in heads?

That depends on your pistons, intended fuel, and target RPM range.

Okay well I don't know what difference fuel makes but I was looking at the 1500 to 6500 rpm range and how do I know what kind of pistons I have?

There should be a part number stamped or etched on them.

edelbrock power package is right on 400 hp with 350 or 383.

Cam and heads for 350 will work just as good with a 383. unless they are too small for the 350 the 383 will be just as happy with them. It could use a little more air/cam but does not need to be over done to make good power.

there should be other numbers on the pistons somewhere, take a few pics of the pistons from all angles and we'll try to figure it out for ya. they need to be clear photos though.

355 Engine Build

Okay i have a block bored to .030 that has stock pistons and crank and what i am trying to figure out is a good and semi economic build that will get me 400+hp and hopefully a similarly close tq as well. Right now i am considering the edelbrock top end kit #2098 and that is going to run me about 1900, i was just wondering if anyone else had any suggestions on a similar performing setup that might save me money without cutting corners. Any advice is greatly appreciated

Jegs heads, Edelbrock manifold, Jones cam. it'll cost about the same and produce a lot more power. Edelbrock makes good manifolds, and real good street carbs, their heads are not bad but are not as good as a lot of other vendors offerings.

Yeah I was planning on going with a 750 cfm edelbrock carb and a matching intake and when it comes to heads is there any specific specs I should look for? Same with cam.

If you're staying with a moderate cam then the edelbrock carb will work very well, for a larger cam though they can be a little tricky to tune and a good aftermarket holley style may be better- but be warned a good carb for a big cam will cost you upwards of $600.

111145-10 CL111145-10 272 278 219 225 .510 .525 110 106 Hyd. Hyd. 1,2
1500-5600 Fair idle, Performance Street, Nice streetable mid range power. 1800+ stall suggested.
cam like that
SHP dart 180s or equal something else
750 CFM carb
performer manifold
9.5:1 C.R.
1 5/8s long tube headers
This would likely make more than 400 HP
