I definitely noticed a difference in acceleration after it was installed, especially at higher RPM. I have the IPD sport exhaust on my '87 240 w/B230F engine, and I'm happy with it. To give you an idea of the price, the last one that sold on ebay went for $41, and prior to that one sold for $71. Another option for a camshaft upgrade that's much cheaper is a K cam, which will give you much better performance at higher rpm while sacrificing low end power. SPG9 lists it for $129 on their site, but I have no idea if they actually have them or not. If you decide to get a VX3 cam you probably will need the adj. The VX3 cam shown on pg.36 is the same as the 'street performance cam' listed on pg.39 (the specs are the same, but I don't know why they list it twice). Would appreciate insights/stories from folks who have 'hopped up' an n/a 240. ratio and avoid pre-ignition? I'm not sure if this would be accomplished by using a headgasket of different thickness, or having the head machined. How much more could be gained with a port and polish and 3-angle valve job? How can I safely increase the comp.

Looks like the 'VX' with their hi-flow exhaust kit would put me at about 132hp. 39 for the same price.įirst, the prices appear to be reasonable ($189), but will I need to replace other valvetrain components when the new cam goes in? Second, how dramatically are the performance characteristics of the engine changed? Also, what is the difference between the 'VX' cam and the street cam? They also have a 'Street Performance Cam' on pg. iPd recommends the 'VX' cam and claims a gain of 12hp. I'm not sure which setup would be best for my b230f. What I'm most interested in is a hi-flow exhaust and cam upgrade. I picked up an iPd catalog a month or so ago and it seems that there are several options for increasing the performance of b21/23/230 engines.
