351W/383 stroker build

It has been a while since this engine build has started, but I am on the home stretch now. I am now waiting on the .060 MLS gaskets for the final push to get this up and running.

69 C90E block .030 ARP main studs and Melling hv pump/ teflon wet gears
Eagle steel crank, 3.75-rods 6.250- Probe forged/ dished pistons 19.3
Comp Cams 35-24-8 hyd roller, Roll Master chain/gear, Howards link bars
Pro Comp heads 200 CC 60 CC chambers
Comp Cams 1.7 rollers
Edelbrock Airgap dual plane/ Barry Grant speed demon 650 vac

I think this will be good for what I want in a 70 F100 short bed.

It will be sporting a fresh AOD and a 9"/ 3.89/True Track/ Daytona support.

Looking forward to driving this rig in September.

Re: 351W/383 stroker build

Just curious why you would go with 383 (chebby number) instead of anything up to 408. Last time I checked (years ago) they all cost the same to build.

Re: 351W/383 stroker build

That should put a grin on your face. I notice your block is out-of-square by your deck checks. It's not necessary for a street engine, but have you considered checking for where the the deck difference between cylinders is from? Side-to-side, it's 4 or 5 thou different between banks, but if the other 4 to 5 thou variation is in your rods or pistons, you could swap them around to put the long ones on the short deck side, and vice-versa to even them out.

PS: Sorry, that's the anal precision-build side of me asking.

The decision was made based on rod ratio for longevity. The minimal HP gain per cubes was negligible as per my application.

PSIG, I had to sleeve a cylinder and deck the block prior to installing the balanced rotating assembly. Then I discovered the .007 total imperfection between the 8 slugs above deck. My mistake was using a 69 block. The Cometic gaskets @.060 will give me a .035 to .042 quench between the unruly slugs and make for a ping free burn on pump gas. Fingers crossed

Well, I like that mistake, and have another '69 block that I intend to do exactly the same with on-purpose.

Yeah it's a mistake I can live with. The compression will be at 10:1 which is just what I wanted.

Re: 351W/383 stroker build

OK, on with the build, I took a cyl to valve measurement with a .047 head gasket using silly putty and have plenty of clearance. = 100" exhaust. Now I will check for other parameters within the basic build. The intake and carb selection will be a Barry Grant 650 vac sec coupled with an airgap and 1" multiple spacer.
