If you're going to maintain carbed fuel control - you'll be looking for the '87 - '88 AMC Eagle 258 Intake manifold - which will mate to your '91 - '93 Jeep 4.0 #7120 casting with little fuss. Then go for the Mr. Gasket $18.95 4bbl. to 2bbl carb manifold adapter - so you can mount a smaller cfm 4bbl on there - like around 390cfm. The late 50s moPars used 4bbls like these - and can be found for next to nothing. Later on - you can buy a Turbo & join the www.blowthruturbo@xxxxxxxxxxxxxxx group - find out how to pressurize the carb and you'll be good for a solid 250HP on stock 258 shortblocks. For those on budgets - and HP crazed - this is the Best Bang for The Bucks. The nice thing is - the Inline 6 allows the Gremlin to handle well in the twisties - and the extra HP of a BlowThru Turbo will make all that parts chasing - worth the efforts. Brien.
