Also you will need to either modify your stock throttle cable bracket or use Edelbrock 8032 throttle bracket. Vortec heads need and bore it to match a 1990 454SS TBI gasket and use a bored 46mm 600cfm TBI unit from and my CUSTOM CHIP,В Which you can now order on the Ordering page on the menu of this site.

combined with the stage 2 level 3 chip though that motor should make around 210hp and 300-320lbs of torque for only $1500 shipped to you. the heads on this engine are essentially TBI heads with altered intake bolt pattern and a level 3 camshaft which will yield 15hp over stock TBI cam. While 260hp is dreaming the 195hp is the more realistic number. I get requests from customers for something cheap that is a little better than stock motor.The heads on this engine do not have EGR provision and to get that power number you need to use the Weiand 8150 intake that ATK sells or use edelbrock 2701 intake and then open center adapter from as well as a bored SBC throttle body at 22psi of fuel pressure on 350 injectors. they do know who I am so tell them brian at sent you and that you are interested in HP94 with a comp cams 08-501-8 roller cam. I tried to get them to list the engine done this way on their site as HP95 but so far they wont. realistic SAE NET numbers should be close to 375hp and 440tq peaking around 5000 rpm to be nice and TBI compatible. while they rate their engines SAE Gross rather than NET which I dont like that is really the only gripe I have.

Now I have talked with ATK which is a well respected engine builder to modify HP94 and install a TBI compatible comp cams 08-501-8 roller cam. I have changed number 3 due to previous issues.

Take option 1 and replace the cam with В for 30hp and torque gain over option 1.

Or They now have remanufactured engines for a good price option.

(2bolt mains) (4bolt mains) This option can make 300hp an 350lbs of torque with good exhaust and the TBI setup listed below option 3.

will support up to 450hp or pretty much the max engine you can run with TBI. NOTE: ANY ENGINE making over 230hp needs to have a fuel pump upgrade. Then also lots of 1 ton trucks with wimpy 350 engines that really need big block or turbo diesel like torque. I have decided to add a couple big block engines on this list as many of you especially 4Г—4 truck owners should consider a good big block as they make more power at lower rpms and so not as necessary to regear for your larger tires as too many 4Г—4вЂ™s out there running poor gearing for the size tire they are running. good performing reliable setups that wonвЂ™t break the bank to bad and are good fuel efficient designs as well. These are 3 TBI Compatible recommendations I have forВ small block Chevy engines. if they are promising 300hp or more and using TBI 350 heads then they are either just lying or using SAE GROSS which you can never replicate in a vehicle. SAE NET numbers are what I will give you when calculating engine power from the specs provided so make sure you also look at the build of any engine online your looking at. Very few places advertise Sae net numbers. A 180hp 350 tbi motor makes a good 230-240hp using Sae gross math. 75 and itвЂ™s much closer to what I estimate power at in the vehicle. This typically yields a number about 20-25% lower than those gross numbers. Sae net is power at flywheel with all those components on engine as it would be in vehicle. The difference is sae gross is power engine makes with no accessories (not even water pump), no air filter and no exhaust off their very large long tune headers that would never fit in a vehicle and no exhaust. In 1972 car manufacturers switched to sae net numbers which is easily half the reason power numbers listed for vehicles in 1972 were dramatically less than 1971. AВ lot of engine builders list engines as Sae gross power which is how factory rated motors prior to 1972. When looking at crate engines on line be sure to ask if their engine power numbers are SAE GROSS or SAE NET. Please look at the bottom of page where it says FINALLY about ignition system.
