So I am in the garage today looking at a pile of parts I can't get rid of, so this got me thinking. What if I built a neat little 355 that looked so inconspicuous but after a pass or two they would go, What??? Here is my recipe,

.030 350 SBC 4 bolt main
Heads Dart 200cc with 49cc chambers for a great 12:1 compression
My smallish 1165-P hyd cam or my 292H CC cam and lifters with stock rocker arms
GM Ported Marine dual plane intake (Z-28 copy) 750-850 carb or a re-worked Q-jet
Stock painted late model valve covers and black air cleaner
1 5/8" headers

Make this think look as junky as possible to hide everything and no chrome or fancy stuff at all.
I love building stuff like this out of crap parts sitting around doing nothing.

Sounds like a rocket layin on the floor in parts

Sounds good to me. What do you think that 355 would rev up to?

I like the concept, but prefer the idea of a heavily worked factory head.

I started a build of a SJ 327 block with an older aftermarket 3.48” SJ crank. I was going to run it in my 57 with ported aluminum speedway motors camel hump heads, modified to take a staggered valve cover, and a heavily worked factory intake. I was hoping to squeak into the 12s with it.

Between my engine being with the slowest machinist in TX and then my C10 jumping it’s timing chain, and both my wife and I taking job relos in different cities, parts not being available, pistons not ordered while I waited 12 weeks for retrofit HR lifters… the build and plans got changed.

I rebuilt the 57s 283, and and plan to sell the 57. I went with a dished Icon piston for the stroked 327. So it can run on 87. It’s just gonna be a rather expensive, albeit gutless, POS that will move the C10 around on 87 octane gas.

Sorry for rambling. I look forward to your build. I know you’ll do it right.

Many years ago, we built a 355 with a pair of the cheaper Dart cast iron heads, true 10:1 compression and the Comp 292H cam. LT-1 type aluminum intake/3310 Holley.
It ran outrageously strong, fun street engine.

Never underestimate the mouse motor, there are some real nasty variations of it out there that can run with the best of them and still live in the street ...(but best in a Vega).

Sounds like an awesome idea! Would love to stuff it in a dirty old elco or gasser and hit the track

Depends on the cam I use, if it's a solid cam 7200 is no problem but the 2 hyd ones will be in the 64-6500 range. I do not trust hyd lifters after that much more RPM.

I would love to use a factory head but the Dart's are just too good to sit on the shelf. 270cfm flow out of the box with no porting and just need a good valve job. Will take a ton of work to get that out of a production head inc. a Vortec head.

I understand, and look forward to seeing your results. There’s something special about looking slow and going fast

Compression seems high for that cam? My favorite low budget engine had the same heads with a larger chamber but used a tight lash circle track solid flat tappet.

Ok, let us in on the fun...

What car is it going in?

 

[WHT/73]

Is that intake cast iron? It has dual bolt patterns rt? Quadrajet/Holley?

My Camaro at first until I can find a new sneaky ride.

How bout a Prius?

 

[WHT/73]

Yes,

Nice! I have an old winters over the counter 70 LT-1 aluminum intake from a complete engine I bought 35yrs ago. I can’t let it go!

 

[68Chevele]

How bout a Prius?

LOL!

 

[Aaron]

What is the fuel for the 355?

 

[jeff swisher]

Sounds fun.
I was bet I could not go in the 13's with a Q jet and iron exhaust manifolds and Q jet iron intake.
Went 13.028 first time at the track.
Single point distributor 186 heads ported that flowed 225 cfm intake and 195 exhaust 1.94-1.50 valves.
270H comp cam, Q jet intake Q jet carb and 3.70 geared limited slip rear end, Uniroyal tiger paws.
Yes intake and exhaust manifolds were ported.

350" .028 piston to head clearance with 5.5 cc flat tops.
Headers and RPM intake put it at 12.55 with same gears and same uniroyal tiger paws.
Cam was 270H and stock rockers and Z springs.

That 292H will go 11's easy with ported 305 heads in a 355" with 10.3 compression
If that build does not go mid 11's you messed up somewhere.

I am sure you will not mess up.
I expect low 11's from you.
