I'm building a stroker and was wondering does anyone have thoughts on my process? I'm going to replace the crankshaft with a stroker crank off ebay sbc already correct sized journals.

Any thoughts? The engine budget is already spread thin as it is, so I'm trying to wrap up the costs. FYI I'm keeping all other parts mostly the same, maybe a throttle body spacer just for a little more air for the With 6" rods can I use stock pistons? Or what do you all suggest? Any link for me for pistons that'll fit right? Does anyone know the compression ratio for the with stock heads and flat top pistons or dish pistons?

I wanna keep it with 87 octane fuel. Forget about the Comp cams stuff. It's sub-par. Your duration at. E: That cam is not as small at the seat than it looks.

However it will not be bigger anywhere else, just at the seat. The opening and seating velocities of those cams are so excessive that they make for noisey valve trains and they beat up lifters. I have lost track of how many street engines I have pulled apart with beat up lifters in them along with one of the XE cams. It's never going to run with that cubic inch engine with 5. Think 6 inch rods, not 5.

Zero deck the block.! Especially with 5. Exhaust cam duration will make that fact even worse. First off all, mileage-vehicle condition-depth of wallet all contribute to what you should do. The 5. The good kits come with programed ECM's and all parts to bolt in.

Also, while you have the engine out, pull the trans and replace the sun shell with a forged unit and replace the torque converter with a stall converter. First step your right. Dump the TBI, it's crap. Swap out the heads to a set of vortec's, add a GMPP vortec intake, and throw on a carb. Maybe swap the cam out too, and you should be around HP or so. Edit: I disagree that TPI is bad for trucks.

Thats what you want in a truck. I dont know if you budgeted balance and blue printing the engine, but its worth it better rpm and talk to the shop doing the motor about a windage tray in the oil pan if they think its necessary. What head chamber size cc are you using.The early systems from are just too old to do much with.

However, these systems were primarily used in the pickup trucks and so they still work fine for low rpm truck applications. If your looking to run a motor over rpms then you really need a different type of injection and the cam choice needs to reflect that rpm max as well or your just asking for a nightmare.

Many still out there with TBI vehicles needing help getting more modern power levels and fuel mileage from older GM throttle body injected vehicles without going to the process of rewiring the vehicle to run a more modern fuel injection system.

I recently blew the motor in my chevy silverado, I brought it to a mech shop and I am having them through in a stroker crank. I have talked to a few mechanics and I have gotten different answers. Some of them say that I will need a chip to get the full benefits from my stroker.

Some say that I will be fine without. Just to make one thing clear, a stroker motor is not just a crank but a crank and connecting rods from a block.


Also be SURE to use a flex plate that is or has been balanced for the crank you are using or you could run into big problems. I know what is necessary to turn a into ajust need to know if a chip will increase performance and or gas milage. Most likely you will need a chip because it will need more fuel.

Also do not expect to be getting any kind of great gas mileage out of a preformance engine like a My brother had a in a cutlass once and he was getting approx hp out of it and there was times depending on the way he drove it, he was refueling it every second day or so.

It will depend on how heavy your right foot is. The way i see itif you are having a performance engine built what does gas mileage really matter. From what i have heard a GM Max Micro tuner from superchips is top of the line. However if you want the best performance and cost isnt that much a concern get a nelson tune for the best computer tuning available.Log in or Sign up.

Stick to mechanical upgrades instead of computer especially on the Tbi's trucks since the computers were very minimal. BigXBearMar 17, Mar 17, 4. My '91 has a JET chip in it.

I'm not sure how much it helped because my cousin installed it when it was still his truck. It also has flat top pistons, a hotter cam, and headers, so I don't know how much the chip helped. Don't figure it hurts it though. Mar 17, 5. I have a hypertec chip. BudgreenMar 17, Mar 17, 6.

See pricing below. Please note this Power Engine will work with just a custom chip. We do recommend the whole turnkey package however because of mileage and wear. Note: Does not include serpentine pulley system. This engine requires aluminum heads and the second generation vortec intake with an adapter for the throttle body modification. One of our new upgrades - please remember we are one of the few in the country that can dyno test TBI throttle body injection engines, and TPI tune port injection engines.

This engine is designed for Off Road, not street use. Please also note that some of these engines require the second generation Vortec heads to accomplish these spec numbers.

We can advise you if this upgrade is required for your needs. This means that you can have after-market iron or aluminum heads, the 8-bolt intake, and adapter at an additional cost.

We have designed a custom CNC adaptor that bolts on the TBI intake so we can bolt on a 4 barrel carburetor to do the initial break-in.

This means if a throttle body is chosen, it will be for radical for off-road application not desirable for the street.

Required modification: the intake manifold has to be counter-bored 50 to 52 mm intake bore size. For larger volume throttle bodies: a 50 to 52 mm intake Edelbrock must be bored for these large horsepower engines. Note: this is for radical engines only!
