swapping a LT1-4 intake to a gen 1 sbc (L98)


Recommended Posts

a few things you should know,if your thinking of swapping a LT1 intake to a L98 engine,look closely at the intake picture

they are available NEW for $230

(1) LT1 used REVERSE FLOW COOLING and NO DISTRIBUTOR (remember it used an OPTI-CRAP ignition,under the water pump)

 

notice theres no place to install the thermostat or distributor!!!! as THE LT1 had that mounted to the water pump housing)

 

(2)LT1 heads and intakes have the ports located about 1/8" higher in the location than L98 heads so gaskets don't line up correctly (THIS CAN CAUSE INTAKE PORTS TO LEAK)

 

(3)mounting bolt angles changed , look at the center two bolt locations

 

yes IT is possible to adapt to your engine, if your going to do it I STRONGLY SUGGEST STARTING WITH THE LT4 intake as it flows better

but be aware that you'll lose low rpm torque, and unless you have installed a larger cam,better heads,headers, and changed rear gear ratios to move the engines average rpm operating range higher too match and significant ability to tune the new combo well after the intake swap is mandatory,the intake swap will be of little value as you will not gain much on the higher rpm end to offset that low rpm loss without those other changes

 

 

CAN IT BE DONE? YES,

IS IT A GOOD IDEA?

THAT STRICTLY DEPENDS ON WHAT OTHER CHANGES YOU HAVE IN MIND TO MATCH THE SWAP.

GENERALLY ITS not A good idea ON A stock L98 ENGINE, but has good potential on a serious engine, simply because its less restrictive to airflow PROVIDED the cam, heads and gearing also allows the engine to use that potential
