Your set-up is AWESOME! You are the only one I have seen on youtube to run a engine like this as if it was in the vehicle with accessories and mufflers!! Maybe, some of these DYNO folks need to take note!! True Engineer!!
Haha, I see what you mean. But this is nothing new, nor is it rare. Imagine putting an engine into a car, only for it to not work. You should take note it seems LOL
There's almost no rotating mass. The flex plate may weigh 3 pounds maybe? No flywheel, no torque converter, so it's gonna rev really fast. It does sound righteous, though.
If your cam makes say 7-8 in at idle a regular old vac reservoir will give you a good brake pedal Like single pattern cams when the lsa is that tight....a few deg split for the weak exh port ought to be fine Love SFT engines no roller bearings to go bad, cheap and run like a mofo. Sound in the interior is to die for THey rev seamlessly never had a hyd truly perform like one. Love to see power number on this. Low $ build most could do
I'm setting up a similar engine, 355, flat top pistons, old school bowtie heads ported, 10 to 1 comp, solid roller 243 257 @ .050 107lsa 1.7 rockers on in. 603 lift 1.6 rockers on exh. 553 lift. Can't wait to see how she runs.
Thank you for videos. Are you running guide plates or self alignment rocker arms. Debating if stock arm will work without guide plates on solid flat tappet. Thank you
Hey I just found your channel saw you run that in the nova video just curious what your DCR is with that cam I’m just starting to wrap my head around cam profiles and how it effects compression I am building a vortec 355 as well my static compression seems to be 10.4.1 and I want to get my DCR right for pump gas any pointers or helpful vids?
That is one of the things I'm trying to figure out now. I have 77 c20 4.11 gears th350 2500 stall. I need a engine for it. Of the engines I have I would stick my 9.2 to 1 compression cc306 camed vortec engine in it.I haven't payed any attention to DCR. I run a cranking compression check. The difference is im testing. I have no problem pulling a engine and make corrections. I haven't ran that high of compression yet. At my current stage of thought process I would put a .041 thousands head gasket on it bring the compression down. I have a comp xe284 on the shelf I would put in and degree it. Thats if I wanted to leave it in. If I didn't mind taking it out I would leave it at 10.4 to 1 and run my xe284. Im sure there are better suited cams. But I usually would take performance over comfort. If you could go with a hydraulic roller I would. I alot depends on what your trying to do. I do plan on making c20 into a 12 seconds cruiser. Im thinking I will be around 4000 lbs with driver.
@@nylegreen261 that sounds pretty much exactly what im trying to accomplish, a 12sec rural road smile. My budget isn’t the greatest but i could probably swing a hydroflattap cam a 2500 stall and 4:11s or 3:73s over the next year, just need enough vaccum for brakes.
@@mjhickson4339 I haven't dealt with vacuum brakes in years. I will have that challenge. Im thinking the my vortec with the cc306 will be fine. Years ago I ran a xe 294 in a 9.5 to 1 sbc 350 with powerbrakes. I drove that car everywhere. I rember alot about the car and nothing about the brakes. Must of been fine. I was 21 at the time.
Its hard to get compression out of these budget builds. This has 1.540 compression height piston. Not one sbc that i have has been decked even if they have been rebuilt in the past.
I see what you mean, with a 9.025 block, 5.7" rod, and 3.48 stroke, you end up with .045 deck height. You're only gasket choice is a .015 steel shim for a .060 piston to head height, not optimal for quench. If you need pistons then just get 1.560 pistons, other wise deck the block .020 - .025 for optimal .035 - .040 quench. With the cams you chose 10.5 - 1 would be minimal for best power l would think.
@@joe-hp4nk cylinder pressure is low. When I got the cam I thought I had more compression to work with. Im going to ro run i think the vortec heads will save it.
Looking forward to see more of that Vortec headed 400 engine !
Nice me too!

I've got a few on here myself
Nice build. So glad it's not painted orange.
It wants to rev! Sounds great
Thanks I can't wait to test it out.
Damn, it revs like a sportbike. That makes me think naughty thoughts!

I'm interested in seeing how that motor runs too. Is that the older phase bowties 186cc runners?
Comps Big mutha thumpr cam that is.
Careful running those 1.7 on a faster ramp cam youre gonna need stout pushrods and springs
Way ahead, .080 wall pushrods and double springs.@@gordocarbo
Sounds awesome 👍.
Thank you

Thank you. I have been running self aligning rockers with the solid flat tappet cams.
Thank you for replying. Which rocker arms you running. Been debating screw in studs and getting guide plates but machine shops are pretty behind
What did you use for feeler guage using self alignment rocker?
Sounds so so awesome my brother.can you please give me the part number and name of those muffer

@@nylegreen261 thanks so much my brother.
Could you do a video detailing your run in stand? Thanks for the video!
No problem
Dod you use the roller lifters or solid
Hi Sir... Are You running the Direct Lube Solid Flat Liters?.... I'm using them now and highly recommend.
Yes howards 91118.

you made the stand to start the engine?
@nob3na322 Yes out of junk laying I had laying around. I will make a video some day on making a cheap run stand.
I thought with the Vortec heads you could only run up to about 480 lift. Did you modify the heads?
If you use a valve spring like a ls6 behive and a 787-16 comp cams retainer. You can run a cam with about .525 lift with the stock heads.
Great videos. Did you pin rocker studs ?
Is it bone stock bottom end
Stock 2442 cast crank. Stock x rod with arp bolts. 1.540 compression height hyperutic piston 4 valve relief flat top.
@@nylegreen261 sounds healthy
It sounds good but doesn’t sound like that long of duration
Check it out in the car. At the race track it had to get up in the rpm's before it started to pull.
thats a bad MF there
Thank you
What rods?
X rods arp bolts. I know I'm pushing it. It hard to do budget builds and get good aftermarket parts. So my limit is usually the rotating assembly.
What’s the static CR ?
9.7 to 1
What's the compression ratio?
9.8 to 1
@@nylegreen261 That's lower than I thought, the 106lsa helps you out there. Be interesting to know what the cylinder pressure is.

What is cam number
Bro I think is this one Howards Cam/Lifter Kit CL110832-06DL same duration and lift
That's the one. I also used their lifters
Phuk ya wats up with 66 ll
Been testing a different motor this one will be coming up next.
Rev it higher 😂
I would if I could.
