I can give an estimate. lol With a 390 holley, headers(any kind), HEI and a lump port head with 1.86 intake valves and stock exhaust valves I'd say about 40 more hp than stock....so close to 170-180 hp I think. I don't remember the hp specs on the 250's as of now. You'd really be wasting time not adding a little more lift on the cam at least. I'd go a step over stock with a cam if I was doing a light build. Comp cams has some good grinds for cheap.

so i think with a good street cam like 0.490 valve lift and duration at 050 212 and lobe 110 can deliver 250 horsepower ! is this true ? |

Head work: 1.86 intake valves 1.60 exhaust valves Be sure to have a at minimum 3 angle valve job and make sure the bowl is opened up as well. No chamber relief will be required. Lump ports. Z/28 valve springs. .030 shave off the head. Block work. .040 over forged aluminum flat top pistons. Ross is a good place to check. Tom Lowe does sell them for cheaper. Those will give you about 9.5.1 compression. A good cam would be comp cams 268H 218@ .050 .499 lift on a 110 lobe center. That'll give you a choppy idle and good RPM range. Here's the cam spec number 61-244-4. Go to their sight and see their camshafts. They have some nice options. Custom grinds are available as well. Stock rods balanced and refitted with ARP studs and bolts. Crankshaft balanced and ground for sure. Add a good intake and headers will a 390 holley or 500 edelbrock and HEI. You should see around 290 hp and 270 torque. Larry aka Twisted 6 can give you some options as well. He's on this forum once in awhile. Tom Langdon at Langdon's stovebolt will also have good advice. Mike at Ravenswood Paint and Body.....hard to get ahold of but a good man as well. lol Tom Lowe has done dyno testing so you could probably get some specs from him.

Re: Tricked-out Chevy six cylinder engines
Just received my offy 2 carb manifold for my 230 from speedway. It appears that there is no way to use any of the original linkage. The installation instructions are very vague. My question is has anyone here have this set up or seen it? The instructions for the linkage kit says to connect it to the original bell crank but that was connected to the original manifold and the offy has no provisions to install the bell crank set up. I thought it was going to be a simple swap out. thanks for any info.

Dual Carb or 2 barrel? Dual carbs may pose a challenge above my pay grade. Or you could fab a pivot on the Offy like the one the cast iron GM intake. Not sure how.

Re: Tricked-out Chevy six cylinder engines
Can you point me to details on how you did this? (Pictures, part#s, etc.) I am about to drop a 292 with the same carb on a Clifford intake in my '63 and have been thinking about throttle strategies. A cable setup sounds much simpler than some of the fab'd-up mechanisms I have seen.
Many thanks...ned. EDIT: I found this thread that answers about all my questions. Thanks TJ! Great work Quote:

Re: Tricked-out Chevy six cylinder engines
I left the original pedal and arm and then made up some short rods to go to the original bellcrank that I mounted sideways. Fabricated a mount off the back of my Edelbrock carb. Been on there for about 10 years now and works perfect. No bad spots in the pedal just nice and smooth.

Re: Tricked-out Chevy six cylinder engines
I think I'm going to send the manifold back and cut my losses unless someone has this set up already operational. If my truck was 3 on the tree it might be easy to set up a cable linkage but with the power glide and kick down bell crank. Nah! Someone has to be running this manifold. the only thing that would make this thing work is to weld a piece off tubing onto it to provide the pivot point for the original bell crank set up.

Re: Tricked-out Chevy six cylinder engines
Mehoff400,
Just curious what's your build plan is? Just started tearing my 250 down for a winter rebuild. Planning on building one with a little attitude as well. Thanks, Pappyx4!
