I was considering putting a 9.2" deck R3 in my Dart. Has anyone done this with headers and accessories from a stock deck height block? Just wondering if there may be any clearance issues with headers and suspension and possibly accessories with the slightly lower deck of the R3. My headers...

Just curious if anyone has any information on the cons of milling a 360 main forged crank for installation in a 340 main block. Does the removal of the material weaken the crank? Would the crank need to be hardened after the machining? Just wondering as I am building a 360 stroker and...

Anyone know the specs on the Mopar performance block P4532435? Do these come in various deck heights or one and if only one would you know what it is? Same question on the lifter angle. Thanks

I am preparing my block to go to the shop. I have yet to pick the shop I will use. What are most people paying for the key maching steps in a quality street strip build including - boring and honing with torque plates - squaring the block - line boring - clean and inspect - sonic check of...

My friend has aset of W2 heads that have been sitting on the shelf for 10 years. Part number is P4876336. It is a closed chamber head. Anyone know if it is a 59 degree or 48 degree tappet head and what the valve angle is - 15 degree or 18 degree? I can't seem to find much information on...

I am getting ready to bring my small block 340 to the shop. I will have it sonic checked before boring. Anyone know the limit that a cylinder bore can be in its thinnest point to ensure a good round bore and proper ring seal? Application will be strip street and shooting for 500HP - 550HP...

Will the Mopar Performance 8 bolt flange cranks bolt up to the standard 6 bolt flywheels or flexplate? If not what flywheel or flex plate is required?

A friend of mine has a set of W2 econo rockers that I was hoping to use on my W2 race heads (milled pedestals). Does anyone know if the econo rockers can be used if I use the race W2 race shafts and stands? Thanks

I have read many articles about oil system modifications for small block engines but there was never much indicated on how to ensure quick and efficient return of oil to the pan to minimize windage around the crank and cam. I have seen pictures of small plates bolted over the cam tunnel but not...

I will be rebuilding my 69 Barracuda's 340 over the winter and was considering upgrading the intake to an Edlebrock RPM. I was wondering if anyone has tried this combo with the stock hood and air cleaner. Any clearance issues? I believe the RPM is 1 inch taller than stock. I was also hoping...

Has anyone used a 9.2" race block. A friend of mine has one he wants to sell. Currently I have a stock deck height 340 with W2 heads. I am concerned the lower deck height may lead to clearance issues with headers, difficulty installing the intake and require more expensive pistons to build...

Any one know if you can run stock J heads or W2/W5 heads with a 48 degree tappet block without issues or if modifications are needed? How about camshaft availability? Thanks

I Was looking to purchase a crank for my project and have seen Mopar Performance cranks with the 8 bolt flange and was wondering if they can be used wth the stock 340 flywheel or flexplate. Thanks

Looking for your input on using an Edelbrock RPM (not the air gap) versus the stock 1969 340 4 barrel manifol on my soon to be built 69 340. I have both manifolds. The engine will be used in a 4 speed Dart with 3.23 to 3.55 gears and near stock engine. I plan to clean up the ports a little...
