allioop, My understanding on the 113 cam was that it was designed as an NHRA cheater cam. It has exaggerated exhaust duration to help compensate for the weak exhaust flow of the stock Buick heads they were forced to run. I suspect that it did work well with your old set-up but, the new heads do not need that compensatory duration because the heads flow better. Get a cam that works with your combo. Heck, email it to Jim and get some really good advice. I took the time, a few weeks ago, to speak with Jim at his shop. Rest assured, he knows how to build more than just race engines. In fact, I get the impression that most of his motors go into very streetable cars.
Ok jim, this was an answer i was looking for, now if you can give me your two cents, do you have a recomendation that will work with my existing gear setup or with a geared up tranny, i want to continue my 200 mile half tank trips. Should I stick with the gs 113 or is there anything else that will work with what i presently have. I do understand that sometimes conservative combinations can yield surprising results.
"I try to get out... but they pull me back in".. Vito Corleone in the Godfather 3 Here is your answer.. http://www.trishieldperf.com/level_1a_engine.htm Cam and buildup specs, with dyno tested results. Brent is on the money, no need to run the 113 style cam with the new heads.. head flow is the number one factor in camshaft selection. My selection for the type of motor you building is the TA 288-94H for the dual plane/exhaust manifold motor, and the TA 288-92H for the single plane/ header version. As a side note, I spoke with Mike at TA today, and he does believe he has the answers and the right parts to make all the lifter trouble we are having a thing of the past. JW
Jim, can you elaborate about the lifter issue? It appears the last engine I did for a friend is having a lifter problem...:af:
