Jul 21st, 2025 | | | | Joined: Mar 2017 Posts: 76 'Bolter | | 'Bolter Joined: Mar 2017 Posts: 76 | It has been a while since I have posted. I am building a 216 for may 40 Chevrolet 1.5 REA express truck. The crank is ground and I have had the rods converted to inserts. I have purchased the insert bearings. I have contacted Ross pistons for the domed pistons. They will make them for me. My question now is on the camshaft. I know this engine is not going to have much more horsepower than 85 horsepower in the truck. What are your thoughts on camshafts, two single carbs and duals? Honestly, I think the factory cam will be fine with a single carb and factory exhaust manifold. I do have the in line book for performance of a 216/235 but I was curious as to thoughts on this. In regards to camshafts, would folks recommend a stock grind or something ground from Howards? I hope Jerry (Hot Rod Lincoln) is doing well.
Thank you

I dimly recall reading about a 261 rebuild/build/assembly being done by Jerry at Stovebolt gathering? I wish I had been able to be there. Phillip, do you just want to see a few Jerry-rebuilds, or, ???? | | | | | Joined: Jun 2001 Posts: 775 Bondo Artiste | | Bondo Artiste Joined: Jun 2001 Posts: 775 | You said you can make a 216 with 258 cubic inches, with full pressure oiling look like a 216 original. So you’ve done it before? But the wallet will need CPR? I was hoping to see this engine. The way you posted made it sound like you have done it before. If you don’t have pics or haven’t done before sorry I misunderstood.

I just spent a week in ICU with blood clots in my lungs. It uses a modified stroke 235 crankshaft and pistons, H beam rods for a Nissan 2.4 liter, a 250 oil pump, and several other major modifications. I've been doing major engine mods for over 60 years.

Listen to your doctor/doctors - do what they tell you to do (and follow their instructions regarding what they tell you not to do). | | | | | Joined: Feb 2004 Posts: 28,674 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 28,674 | Similar crankshaft modifications can take a 235 to 270 cubic inches and a 261 to over 300.
